Did this cap care but just not trust me? Or is he just a player?

I'm a taurus and I met this cap 2 years ago. he didnt want anything serious so a few months later i got a bf. I heard that he claimed i was his dream girl and the one who got away for a whole year he would talk about how i was the only girl he would of dated in college. 4 months ago my sag bf broke up with me and I reached out to cap after 2 weeks. It was going amazing and I really liked him. He took me on dates told me he liked me.

He just was always asking me if my ex and i were texting or if anything was up. I always said nothing was up but after 3 months of talking he stopped contacting me and didn't reply. I saw him out and he told me he was worried about the ex situation & said he didnt think we were comfortable w each other but we were all romantic again cause he can't help it when he sees me. More time passed and I did start randomly hanging out w my ex when we were out so in 1 month i would see both of them like 2 times. Then my ex said he wanted to date me again and has been putting in effort & talks to me every day. Cap saw me and him out and gave me a mean look twice. he contacted me to tell him when i leave to go home and i did but he never replied. So i texted him telling him i was confused and he said that he doesn't want anything serious and i do so thats why it doesn't work. All his friends said he would of been with me and doesn't talk to other girls and wouldn't but he doesn't want to be serious. He is still mad that im back with my ex though. I just don't get why he cares to tell me that and give me looks but doesn't want to try to be with me then? I love my sag bf but I get bored because we are too comfortable and i still hold some resentment cause hes the one who broken my heart. The cap always made me feel so special and was so much fun and I just miss the passion in that. I ended up asking why he had done all he did and the cap hasn't responded and it's been 2 days. Maybe I should just delete him off everything. Idk

Please help me with some advice!! It would be so greatly appreciated! So confused 😢
