Heres the story. My S/O and I who are engaged seem to be breaking apart.
I think I don't give her enough space among other things. I would do anything to make this relationship work but I don't even think she wants to work at it. She talks to her guys friends online for like what seems like all day. Pretty much whenever she's on the computer she is typing to them. This obviously makes me jealous. She knows this but just gets pissed when I bring it up. She wants to go out with her friends which are almost all guys which I have no problem it's just she doesn't want me to meet them. She said its because she doesnt want me to become friends with them encase we break up(so her friends arent my friends in other words). WTF she shouldnt be thinking that way to begin with right? She tells me problems every once and a while I tell ok lets work on them, then she gets pissed and doesnt want to talk about them. She says I'm boring. What I need is an outside opinion. Do you based on the information think we should break? Or any addice would be great as well. I really need this guys I can't keep going not knowing whether she really loves me and what I should do.
