Is he leading me on or am I overthinking

I know I sound crazy and obsessive. But I’ve been seeing a guy for a little over a month. We’ve spent a lot of time together and have spent multiple days in a row together. And within this month we talked about being exclusive but wanting to go slow. He made it very clear on multiple occasions how much he liked me and that he could see us going somewhere. When we started talking he was also talking to an old friend back home that was trying to get at him. Now at the time I didn’t know this I just thought she was a friend. But we met and really hit it off and at first he just told me they were friends and I didn’t care cause we only knew each other for a little. But one night we’re getting ready for bed and this “ friend” keeps blowing up his phone. Apparently she was drunk. The first time he answered it was while I was in the bathroom and took it outside. He came back in and was like “gosh she’s crazy and drunk, she’s crying and just can’t get words out straight” so I just said okay not trying to make a big deal but then she keeps blowing up his phone. So he answered again and took it out of the room. At this point I was confused. Anyway he comes back in the room and starts off with “I know this seems suspicious and I’m sorry, I know you have questions so ask them.” I really didn’t know what to say. Long story short he had still been talking to her in that way but he just didn’t know how to tell her he wasn’t interested in her anymore and met someone else. I told him that if he wanted to be with her then that was fine, but then we’d be done no hard feelings. He said he didn’t want her like that and wanted me. We talked about it for a while and came to an agreement that he would deal with it. Now when we first met he told me he was going home for her birthday. But then like 2 weeks later said he didn’t want to go home and wanted to cancel the trip but he already told his family so he was still gonna go. So he told me that he would talk to her then and deal with it. So flash forward to last weekend we spent three days together. It was amazing we talked about really deep personal things and the future and all the things we want to do together. I talked to him about how I was scared he was gonna get weird while he was gone and come back not wanting me anymore cause that’s happened in the past. And he told me he was nervous that I was gonna leave him and was too good to be true. We got really deep into this and he told me he was gonna get weird when he was home but that was only because he would be super busy and barely be on his phone. So I chose to believe him. But I’m on day 6 of 14 of his trip and he texted me very little since he left. He did call me for 10 minutes the other day while he was driving and we talked a little and joked around. But then after I texted him and he never got back to me till 5pm the next day. And I’m not gonna lie I’m the type of person who will check a snap score and his will go go up a few points while he ignores my message. I know he warned me about him being weird but all my trust issues are flaring up. I really like this guy and we actually click very well. He’s been really good at communicating his feelings and what he wants or so I thought. Should I sit around and trust him while he’s back home or should I just tell him that it’s not worth the anxiety of the situation and call it?
