Please, I need an opinion about this

Alright so this is a long story so please bear with me, I need help.
So, I met this guy through a dating app. He lives in another city which is 2:30 hours away from my city.
At first, I didn’t take it so seriously because I never did with these apps but this time was different. I liked talking to him; we had so much in common and we flirted a lot. Days later we sexted, which was unexpected for both of us. He was sweet when I told him I didn’t have any experience with that and we spent all night talking after that about important stuff, he used to open up after those sexting sessions.

We continued talking through texts because we both don’t like phone calls, I know weird, but anyway, he told me about some traumatic experiences of his past, things I could relate. The next day he didn’t text me as he usually did, there’s where I started to feel anxious (I suffer from anxiety as well), I started to question myself and what could’ve done to make him feel better the past night, so I texted him and asked him if everything was ok because he was acting distant (don’t ask me how I know that through texts lol), he said yeah, he just has times when he’s down and pulls away from the people around him. I understood that and we continued chatting.

As the days went by, we talked a lot and we also had some sexting sessions but I was getting more and more anxious because he confused me with his mixed signals and also because I don’t see sex as something casual even this sexting thing, that’s just who I am, so even that was big for me. Anyway, some days he was caring and like I said we talked a lot, and he even told me he felt this connection with me, and other days he would be distant and cold, especially when he was busy with his son or his work (again, I understand all of that, we all have responsibilities, it was me who was getting anxious).

One Sunday we were already talking non-stop for 2 weeks, we started talking at midday and we went on for a few hours, then he didn’t reply back and that was fine because I knew he was with his kid and all, but then at 9pm, I was starting to feel anxious about other subjects and the fact he was online and wasn’t replying to my last message, also the night before we had a particularly intense sexting session so I was feeling vulnerable that day because remember when I said he used to open up after a sexting session? well not that time, instead he acted a little bit cold so I was worried about that.

I texted him instead and we did a bit of small talk, something didn’t feel right and I was having a full anxiety attack by then, I told him that and… he saw my message but he didn’t reply me back until 4 days later.

During that time we didn’t talk, he saw my stories on WhatsApp and he was online on the app we met, even though he told me those conversations we other girls have died. He came back 4 days later and told me he was sorry, that he was dealing with some personal issues as well. I was angry and hurt and let him know that but I gave him a second chance. So we resumed our pen pal situation but I was getting more and more anxious because most of the days he was replying to my messages 3, 4, 5 hours later, sometimes he would just ignore me and sometimes we were chatting again as nothing happened… I was anxious because I was afraid he would disappear again, so I was acting like a junkie waiting for his texts.

One day I asked him if we ever were going to meet, and he said: “yeah sure, someday” whereas before his disappearing he told me that he travelled a lot so it was quite possible. Another day I asked him what was he expecting of this thing we were having and he told me: “Look I run a business, I have a son and you have your work as well and we have a pandemic at large and we are many miles away…” I like talking to you and that’s what we’ve got right now, I’m no one to make plans”.

Another thing is that, even though I don’t like phone calls as well, I wanted to hear his voice as I couldn’t physically meet him, he always had excuses, he wouldn’t even send me voice messages even though I sent him some.

One night he was acting “jealous” because I was talking to another guy on the phone. That night he told me: “I want you to be mine, do you want me to be yours?” I wasn’t expecting that so we ended up having sexting again… I know I’m such a fool. I felt empty afterwards, especially because the next day he was acting distant again.

That same week I had a date with another guy and I got drunk because the date was terrible, so I sent him some voice messages while drunk. I was acting like a bitch but I guess I just wanted some reaction from him, I got nothing. You see sometimes when I’m drunk I get sad, we were having a consistent conversation that night so I opened up to him again and told him some of my issues… he didn’t reply back until 3am when my last message was at 9:30pm, he wasn’t expecting I was awake at that time.

Anyway, that same week I decided I had enough because I was losing myself and getting so anxious about the situation that I thought that I needed to take some time. So, after he sent me some useless text on Thursday, I didn’t reply back until Friday with the following text: “Hey, look I like you and I like talking to you but I don’t see this is going anywhere so I’m going to take some space before I get any more closer. Anyway, I hope you have a great weekend, xx” and… he saw my text and never answer me back, that was a week ago.

Now I know no response is a response but I’m still confused. The fact that he didn’t reply me back is because he’s angry at me? or because he’s relieved? or he just doesn’t care? I don’t know, I don’t want to fool myself.

I decided to go no contact for 3 weeks, I did it for me. The question is should I contact him after those 3 weeks are over? or should I let him go?
