First of all.. You have to put that mistake that she made behind you. Everyone makes mistakes that's how people grow wiser!





You have to learn how to appreciate her. I can tell you love her and you want it to work. Well your the only problem in the relationship so u better fix it fast cuz it seems like u guys have something special and your going to be very heartbroken if anything goes wrong.





You should just keep ur mouth shut! If you have nothing to say than don't say anything at all. You have to learn how to control your mouth man cuz if u don't then you'll have even bigger problems in the future.





All u really gotta do is respect her.. And that's why u have to let that mistake she made go to the past cuz if u don't forget it then you'll never make her happy and you'll never move forward.





Do to her like she does to you.. Love her, respect her, and try to keep her happy.. If u want her to be happy then don't let her get upset or mad.





Ur the only person that she truely loves and if u don't try hard to respect her than that's just sad. But I think that u could do it.. Ur already trying by just asking for help.I need of relationship advice?
