Upset AND LW CONFUSED

me and my ex boyfriend just had a mutual breakup because he believed that his feelings were not as strong as he expected them in comparison to the first time. We dated for 9 months (first love, 16) and had a horrible breakup filled with resentment and silence, and then after 5 months apart we reunited extremely quick for 2 months until Saturday. Although I have become a much better person than the first time and he recognizes how amazing I am, and even says he might not find anything like me, he just doesn't feel it. This he believes this has contributed to the fact that he doesn't support me or want to invest into me like I do into him, prompting me to say that it's not worth my time. Due to the quick decision he made and all the other problems I could point out with his reasoning, im having a difficult time moving on and need some help! Also, he texts/snaps me to check up on me and says he's doing a lot better now and is already good? But still texts me sometimes like we're still in the relationship. I have no idea what I want, but it just seems like he doesn't want to solve the problem but wants to be "friends"? Is it as simple as that? I just can't figure out what he's thinking.
