<human>: Can you provide a brief overview of the text?

Hi All, I don't really know where to start so I'll just start blurting stuff out.

We've been having some issues for quite a while in our relationships, she has serious trust issues, insecurity and is emotionally abusive.

I feel like I can't do anything without being in the wrong, if a female co-worker says bye to me or a female friend adds me on Facebook I get the whole "Who is that? Why you haven't you told me about them before?" She'll search people I mention and judge whether they're prettier than her... If I do actually add any female friends on social media she just starts talking shit about them or their actions until it's easier to just get delete them to avoid the trouble.

I feel like she also tries to lure me into making statements she can use against me eg. "Look at my friend in this picture, isn't she so much more pretty than me?"

If we're not talking all day long she freaks out, if I only get to see her 2-3 times a week she freaks out.

If I want to spend time with my friends she starts acting like it's an issue but won't tell me what's wrong even if I ask.

I told her last weekend that I don't feel like we have a connection anymore and she started screaming, crying and saying she was going to kill herself.

I told her about all the issues I have and she promised she'd change but I think it's too late...

I feel like my feelings have already changed for her and maybe I resent her? Like I used to love spending time with her and talking to her but now I don't even want to see her.

I feel like I enjoy myself more talking to other people and being around other people.

Normally after we have a big blow up or I'm angry about something it normally blows over the next day and I just kinda get over it - but this time it feels different.

Is it wrong of me to feel this way? And does this mean it's the end? I've never been in another relationship so I'm not quite sure.
<bot>: How do I know when it's time to leave? Is this just another incident that will blow over and then all be fine? How do you even end a long term relationship?
