So as of late, my girlfriend of over a year now has kept on having "doubts" about if our relationship is going to work out or not. I love her deeply, and she says she loves me, but it always seems like she doesn't put forth the effort to deal with problems in the relationship. I myself try my hardest to fix the little things and all, but it never seems the be enough. Everything goes fine for a while, then she just goes into some kind of "phase".
it's counter intuitive, but you leave her alone.
don't contact her and get on with your own hobbies or whatever it is that you do in your life. hang out with your friends.
OP here, thanks...yeah, I'm using this time to myself. Still hoping that everything ends well.
I hope it does turn out alright for you too OP these kind of situations are terrible. I've never been in a relationship for over a year but the last one I was in ended in similar conditions as yours I let her alone for a couple days and then when I called her she was with some other guy. This actually happened to me twice with different girls. I don't know what to do in these situations either I wrote a really emotional letter once and it worked well but it depends on the girl. I wish I could help.
OP, it sounds like you need to get out of the relationship. I'm sorry to say this but you need to move on if you are truely trying to fix the relationship and she isn't trying then you have to say goodbye. The relationship is not a healthy one, for either of you. If you feel you need to stay with her, then sit down with her and talk again.
I agree with >>5.
People never improve, and usually get worse as time goes on. If things aren't working out now, just wait.
