im make myself upset

Try and move on. Although it will be hard - dwelling on the past won't help you. 3 years is a long time to be with someone only to have them hurt you - twice. Try and get out, do things with friends and family, hobbies etc. You will recover.

Good luck.

One hurt is fine. Pain is going to happen in a relationship weather its someting like cheating or lieing. But you'll get over it in time. and if not. talk to someone about it. someone who'll listen. And if that doesnt work. Talk to him about it. it may seem hard, but my x boyfriend (for a year) cheated on me. After about two months i still hated it. but i loved him. Then, i waited... and talked to my best friend about it. she didnt give me advise, but it was great to get my feelings out and i felt better. Then after i was getting over it... he did it again. (because i didnt talk to him about how serious we were) But i ended up breaking up with him. And i was hurt. But in time i got over it. And now i found someone better.
i dontknow really what you should do. But i gave my best answer.

Do what you have to. just avoid as much hurt as you can.
