Trust Issues or Valid Concern??

So I recently got into a new relationship after having one that damaged me pretty badly. I'm over him, but I think it left some lasting effects on me. There was basically no communication from him, and in the end, I felt really betrayed and hurt because he would say that he liked me but never texted or made any effort whatsoever. I was really close with him and shared a lot of my issues, so when he started getting distant I felt like I had pushed him away. The next sort of relationship I got into was similar, the guy said he liked me but was distant and when I finally asked him if he saw us being a thing or if he just wanted his dick sucked he said he didn't see us being anything. This has left me feeling pretty insecure and unlikeable and generally over the male population. I know it may not seem like a big deal, but I really loved the guy I was talking about prior. When I met the guy I'm currently with, he immediately showed interest in me and still makes it clear that he likes me and wants to be with me. Despite that, I didn't really believe him and I was convinced that he was just playing me. Recently, he's been texting way less and it really freaked me out so I took a step back. He communicated with me that he felt that I hadn't been showing interest and I told him it's because he's been texting less. He told me he's just gotten busy with school and sports which I accept but he won't text me at all unless I text first, and we said we were going to hang out on two separate occasions which he flaked out on. I don't want to overreact and I don't want to seem needy when I talk to him about it. I can't tell if I'm just scared to have a repeat of my last relationship or if he's genuinely losing interest. I feel a little stupid being concerned about it because he says he wants to see me too and he misses me, but his actions don't really reflect that.

TL;DR: My last relationship and other factors gave me major trust issues and I can't tell if this boy is actually losing interest in me or if I'm just scared.
