Just as the title says. I've been dating someone for a few months now (though we've known each other for a few years now) and lately I can't shake the feeling that they're going to leave me or suddenly want to break up. It's like something clicked in my brain and now I'm more attached than ever. I used to be fine with them not texting me at all, and I used to sometimes think "I'd be fine if they left me, I'm independent" but not now. Recently, they haven't been texting as much (they're a bad texter) and then I log onto Xbox and see them in a party playing games with another friend and the jealousy creeps up on me. All I can think is "well fuck this, they obviously prefer this person over me, they want to break up, they're going to leave me, etc." and I proceed to have a breakdown. I have FB Messenger (which is a huge trigger) and saw that they clicked a group chat to read the messages but not my personal messages and freaked out even more. It's like I'm in my previous (abusive) relationship again. It fucked me up a lot. I feel like I'm acting like a fucking child but I'm 22..
