I will keep this short, i'm 24 y/o and was broken up with 6 weeks ago by my gf, we dated for 7 months and lived together for 1 month. We had plans for the future and all that. We had just come back from a romantic couples vacation when she went home she made out with an old crush that she hadn't seen in awhile. Then came back to my parents house and broke up with me 1 week later. I found out through a mutual friend what she did and she did eventually tell me.
I just don't understand how 1.) someone can do that when they were in a healthy relationship and said all the things like I love you, can't wait to get a place of our own, your the best thing in my life..... Then BAM go and make out with someone? And for myself this was the first time I've ever been cheated on and it happened to be from the the girl that I NEVER thought would do that and loved the most and saw a real future with. How do you ever trust a new partner again?
My ex seemed like such a genuine, nice and awesome girl and I never saw cheating as a part of her personality. How can I make sure that this doesn't happen again, because the pain of being cheated on is just too much. I can take a breakup like a man if we try and work on things but they just don't work out. But this last relationship has me wondering if I can trust someone again. It was just the way it happened too, move in together 4 weeks ago, come back from an intimate vacation and 2 days later she cheats on me. It's amazing how you think you really know someone. TIA for the replies.
