Pisces Ex Using Me ?

Hey So I was with a Pisces guy for a year. I was his first gf in about 13 years. He didn’t do relationships but I guess he thought he could try with me. We broke up after a huge PETTY argument. He ghosted me & I was pissed (I’m Aquarius) so I dropped off his belongings on his porch. We did speak briefly a few weeks later & his energy was off. I was getting he was angry at me. He told me he didn’t want to talk to me anymore, he didn’t owe me anything & etc ( I’m trying to keep this short as possible) so I apologized for my part & left him alone. Fast forward 6 months later, he calls asking me to help him pick up his car.. I was happy to hear from him but instantly felt used. I was confused on how he could go from hating me to calling me out of the blue for a favor. I didn’t help him cause I refuse to be used. After he called, I realize I still has feelings so I called him & he basically said he doesn’t know why I think about him lol I also know he was with a girl but he wasn’t serious about him, so I felt it alone again. He then calls me ago 2 months later asking for another favor .. ummm sir why do you keep calling me lol ask your new girl. He Adamant that he not in a relationship so I say why don’t you ask the girl who your messing with or whatever the situation is. He becomes frustrated and asks” why would I ask her” and brings up so much irrelevant topics then says “you know what I’ll ask her “ & hangs up.. so I text me and ask him to leave me alone, that I’ve accepted that he doesn’t want to be with me & I want to move on. The next day, I go to the girls page (she’s 19 Leo he’s 27) & she’s in his car. So now I’m pissed again cause if I would have helped him, he would have used the money to go see her. So I text him telling him he’s a user & I wish I never met him a bunch of other things. I deleted the text & blocked his number.

It hasn’t been a month yet & I feel like I’ve been living in a fantasy world. I spoke to the girl & she told me they’ve been talking for almost a year (we haven’t been broken up for a year yet). Before I knew this, I thought I was the reason for the break up. Now, I see he wasn’t faithful in the 1st place. & for him to use me like I was nothing is triggering. I had to block him from coming back ‘cause no matter how many times I say leave me alone he comes back for another favor. Makes me question does he really need a favor or is it an excuse to contact me. But if I call him, he’ll be very vague & distant. Also, I just don’t understand how someone can say I’m their soulmate but cheat on me & treat me like I’m nothing. I met his family & friends & he met mines too but do I really mean nothing to him now ? I know for a fact (or maybe not haha) that I’m being used but I’m still confused (& overthinking)

Please give me some insight

What more insight do you need? His actions say it all. Stop listening to his words.
