When your partner has the control over the relationship?
I am very much in love with my girlfriend. We have been going out for 2 and a half years now and we are just made for each other. However, like all couples we argue now and again (recently more often) and what I have found is because I am so scared of losing her I don't feel I can ever tell her she might be in the wrong. I let her lecture me but it doesn't work the other way round because she is fairly stubborn and will argue to the point of saying well I'm not happy, hinting if I don't change she will leave. I don't mean to paint my girlfriend in a bad light she is the nicest person I have ever met and wouldn't be mean to anyone but I feel like she has the control just because I love her so much and don't want to lose her.
What do you do to get them to realize that they might be wrong? Or to gain some control?
