I miss him so bad, we didn't technically break up, but I just can't even rn

Be honest with him and yourself. If you're not comfortable being in a polyamorous relationship, then you need to remove yourself from that situation. Let him know that you understand this is who he is and you shouldn't ask him to change for you, but admit that you need a monogamous relationship. Either he will have to compromise for you or you will have to end it with him... That's not meant as an ultimatum; it's simply a statement of fact about the situation.

In a poly relationship, you have to be strong enough to put aside feelings of inadequacy and jealousy for the greater good of the relationship. Not everyone can do that. Most people, in fact, have trouble with that. Admitting this to him and yourself is a sign of maturity. Not holding it against him if you have to let him go? It hurts, but it is also a sign of maturity.

There will be other guys.

Yeah i agree

Okay listen, I'm polyamorous, That doesn't mean one isn't enough for me, It means I can share my love with more people, So that means, You will still be loved, Just like before, It's a little complicated, But you'll be fine, Hell, Just ask him if you can meet his other date, Maybe you can be friends

Periods, Reaper. Commas don't replace periods. :-P~

Fair enough

i've been in a relationship with someone whos poly before, it kinda hurts (mine had 15 other gfs .-.), but u have to learn that its not that ur 'not enough', he just has feelings for u AND someone else :3
its nothing u did or didn't do, in fact, u accepting him probably makes him feel great bc u love him like that :)
pls dont cry qwq

I struggled with this for a while

maybe tell him your fine with him being poly but your not emotionally ready to date somebody who is poly tell him how you feel

Well, the thing you have to remember is: It's not about you. It's not that you're "not enough". It's not something you did or didn't do. It's just that he loves you and also seems to like/love someone else. The thing you need to think about is if you can handle that or not. If you can't you owe it to your boyfriend to tell him that. Because it doesn't work if either of you is unhappy. But remember: It's not you. Trust me.

just cry till you cant anymore

well the thing is is that i know people who pretend they are poly just so they can cheat without keeping secrets. so...maybe...he did that?
