TLDR: The guy I’ve been talking to since June doesn’t call/text me very often at all anymore, should I let him go?

So I’ve been talking to this guy I met on tinder from mid June, and we seem to have liked each other. He lives about an hour away from me in his own place and he has two kids as well like me. He and his baby mother are not together supposedly, and haven’t been for about a year now. He does have his kids 50% of the time and between that and the distance it does make it hard for me and him to spend time with each other so I’ve been talking to this guy I met on tinder from mid June, and we seem to have liked each other.

He does have his kids 50% of the time and between that and the distance it does make it hard for me and him to spend time with each other... especially since my kids are young too..

The last time I saw him was two weeks ago, That was the first time we had sex. I’ve seen him about three times since we started talking in June, so it’s been pretty hard. I’ve noticed however that he doesn’t call /video chat me very often anymore, Whereas when we had started to talk it would be daily if not every other day. I’m not sure if he’s not interested in me anymore or what it could be?

He is a busy man providing for his two children as he works a 9-to-5 job as well as does a side business outside of his work hours so I understand that… However I do see him online on Instagram and it annoys me because he would ignore my messages on WhatsApp but be online on Instagram and just seems like he doesn’t make the effort anymore… I don’t know if it’s my responsibility to start calling him and video chatting him or if I should just leave it alone? I have tried to reach out with calls and text messages before but he like I said before ignores it or doesn’t bother to call me back and it just seems like maybe it’s not worth the stress… And I’m not 100% sure if he’s over his baby mother as well so I’m kind of speculating at this point...

Usually I do go to see him as I have a car and he has his own place which makes things easier but I want to see him tomorrow but I’m not sure if I should bring it up or wait to see if you would ask me? He always seems to be excited to see me and doesnt seem to have a problem with me telling him that I’ll be coming over the last few times ..but I don’t want to seem like I’m always inviting myself over… any advice?
