Should I be worried?

I’ve been talking to this guy for months. We went on a handful of dates prior to quarantine. We were off to a great start and then the virus hit and we couldn’t hang out. We text every day. A month ago I texted him saying I wish he was at my place and he said he did too. I asked him if he really did and he said he’s sorry that he’s been distant. He has a little kid, works, goes to school, and had to move out of his house and said he doesn’t want to let me down because he doesn’t know if he can’t give me what I want (as in a relationship rn). I told him I liked taking to him and didn’t want to stop. He told me he does too and didn’t mean that at all. I was confused but the past two weeks things have been good. He’s been texting quickly all day. I sent him a pic 3 days ago and told him I don’t send them to anyone but him and he said he’s glad I don’t. I took that as he’s happy I’m not talking to any other guy and he’s doing the same. Since that day, he’s been sort of mia. I noticed he followed a girl on insta, which shouldn’t be a big deal. Then I noticed his snap score when up a bunch since this morning. He could be snapping a guy friend but idk. He’s still texting me as usual and even texted me first today, but idk ??? However last night I did say that the wait to hang out with him is killing me and he said him as well. Am I just overthinking this all? What do I do? Like how could it change from 3 days ago from saying he’s glad I’m not sending pics to others and sending me kissy emojis to this?
