Toxic relationship please read

Need advice, So I met my boyfriend back in 2023 when we first got together it was just us but then he started mentioning to me about being in a poly relationship because he’s into the whole poly thing. I explained to him that I wasn’t into that so for a while he left it alone but the third month of us being together he bought it back up trying to convince me that it’s more to just sex when it comes to a poly relationship.

While is being together I knew of his family and his family knew of me but I never met them for some reason and I always wanted to he knew where I lived but I didn’t know where he lived till this day I still don’t know where he lives and never met his family. When I started to ask him why I haven’t I met his family yet but he met mine it was always an excuse,sex is great,when we see each other is all lovey dovey and all about me/us he lets it be known that I’m his and he mine when we are together,communication is bad when we are not around each other some days I would hear from him and other day I don’t hear anything from him not a call or a text message. When we do finally speak he act like everything is fine when really I’m hurt he talks to me like he’s trying to make things sound good when it’s not trying to convince me to for get about the negative it’s like he know what he’s doing when he sweet talks me.

There was also a pregnancy scare when he found out I was pregnant he disappeared on me and didn’t hear from him in a while I ended up having an abortion he was never there. Recently 2024 a year later we reconnected I also agreed to do the poly thing with rules alone because I still loved him so much and wanted to be with him to see if things would work but it’s still the same bullshit and I’m catching feelings again and trying to act like I’m fine and I don’t need him so I could move on but all I could do is think about him and checking my phone to see if he called or texted me but still nothing yet. I know what to do but it still hurts because I love him so much.

Ladies or men have you ever loved someone before that it hurts so bad ? Or loved someone that you would do anything to make it work even thought that’s not what you really want to do ?
