i don't know what to do or think

so, l broke up with my 3 years boyfriend 3 weeks ago. this is our third time breaking up, and I am pretty sure that it is the last time because we won't get back.

my problem isn't about it, is about this:

when we broke up the second time, I met a guy that helped me through the process because I was really bad mood because I want him back (not this case). this guy was joy in earth; he made me smile, told me cute things, etc. he was a very special person in my life.

when I got back with my ex, we had to stop talking because my ex didn't want him and that got uf a lot of problems, so I had to blocked him from everything.

1 year later (right now), and after we broke up, I started talking with this guy again, and he told me that the last time we spoke, I liked him a lot and he wanted to be with me at that time. we also started talking about his actual life and that even though we didn't talk, he now would want something with me if we lived in the same country (he moved); that's super cute and bla bla bla.

the problem is: he also told me that one friend caught his eyes, and that he wanted something with her time ago; but that supposedly "he didn't want something with her now because he is feeling something again for me". he told me that when we started talking, he didn't talk with her again because he started re having feelings for me.

yesterday, I went to a party and this girl was there; she told me that they were (she and he) talking on tuesday and that they had a fight. she also explained me the fight. I told him what she said and he got really mad and bad because he says that that was not what really happened in the fight, that she is a lier, etc.

even though he told me that when we started talking, all feelings for her disappeared, this shows me that he wants to be with her and that I am nothing in his life. the problem is that I am catching feelings for him and that I am hurt about him getting hurt for someone that doesn't want him as I want him.

what should I do? please, help
