I read your advice columns frequently and think you give wonderful advice and commend you for taking your time to do so!Here’s my problem. I am a 19yr old female who for the past 4 years was going out with a 26yr old. We started going out when I was 16 and he was 22. We were engaged for the past year, and we have lived together for 3 and a hlaf years. The past year was a time of fighting, guilt trips and getting treated like crap!(Can I say that on here?-sorry)So, after trying everything from councelling to’talk time’, to walks and romantic dinners, I decided to go away for two weeks to visit family. Everyone has said I should have broken up with him a long time ago because of all the mean and horrible things he did to me.Here’s the problem: I just got back today from my trip only to find out that during our 2 week break, he slept with me bestfriend. Being older he’s had his share of women. I, on the otherhand, have only slept with him. It’s over, I would never be with someone who cheated on me. He knew before I left that it was just a ‘ break’ not breaking up. It was a time for both of us to thinkI have no idea what to do. I am so hurt and I feel so betrayed. You might get this question alot, but I’d really appreciate it if you answer it once more. What do I do?! This was my first serious boyfriend. The only man I have ever slept with! All I have know for 4 years! I’ve been staying at my parents for about a month. (For 2 weeks before I left to visit family). So, I am not living with him or planning on getting back together.My question being: how do I get over this great betrayal? I am so, so hurt. All I did throughout the last year was get hurt, but kept trying to make the relationship work. How do I stop my depression? I know it will get worse. What do I do? PLEASE help me! I can’t deal with this.
