He said he likes me but actions says otherwise

I’ve been in limbo with this guy for a few months – he told me he liked me November 2019 but what he says and does do not match up.

Firstly, what was weird about him telling me he liked me was that he mentioned that he had liked me when he first met me in July and it faded but he had begun to like me again. Could never figure out what this meant or why it faded in the first place but I let it be

Following the confession, I didn’t give a definite answer because I wasn’t sure I wanted to get invested and he had also mentioned he wasn’t ready for a relationship. For a while we maintained a FWB relationship until I had to go out of town for a bit over a month. We texted occasionally but not everyday. There would be sweet “I miss you” at times but there would also be periods of long silences on both our ends because neither of us initiated.

When I returned, he met me at my house but there was no contact for nearly a week after that. Then I suddenly got a call from him saying he had a bad day and needed someone to talk to, I had a talk with him and eventually stayed the night. But immediately after he flaked on our lunch plans the next day. Again, there was no contact from both sides because I was busy with school and him with attachments. When we began talking, it seemed natural because he would ask me questions and be interested in my life.

I subsequently went on a 2 week holiday to take some time to myself. But he would send me posts and social media and I would reply in the most neutral friendly manner I could. As a way of reciprocation, I did send him pictures and funny content. But I realised that he did not even ask when I was going to return – he might be busy with his attachment but I don’t want to be giving him excuses. Also, when I ask him how his day way he sometimes doesn’t reply to that question and replies to something else entirely.

What do his actions mean??
