I would talk through things first, figure out why he cheated (does he have a history of this?), before making a decision to get back together or not. Talk about how it made you feel and that even if you can forgive this one time, you won't be able to in the future. Cheating is never a "good" thing, but sometimes it does make you realize what you had been taking for granted, what/who you really want. It puts things into perspective even if it's a terrible thing to find out about the person you like/love.

In no way, shape or form do I believe that cheating is remotely ok or right. However, I do believe in second chances if the situation calls for it. Maybe this is a time to sit down face to face and speak calmly about what happened. Ask him why he did it - and not let him give you the answer of "Oh it didn't mean anything" because to you it does. Sometimes relationships are more complicated than we think and it's up to us to not give up, but to dig deeper and find out what the root of the error was. I'm not saying to go back and I'm not saying to forget - but sometimes forgiving in the right situation is the best thing for everybody. Take a hard look at who you are - like Lady Reed says - you are beautiful...ask yourself if this relationship is worth saving and if it is, work at it.
Good luck!!

I'm so sorry that happened to you, but I'm so proud of your strength for calling him out and refusing to allow yourself to be disrespected in that way. Look at you! You're gorgeous, and you have a beautiful child to raise. Is this relationship worth saving to you? Is it one you want your baby to be raised within? If so, maybe you can overcome it if this was truly a one-time mistake. Do you think you can trust him? Only you know the answer for sure. If you do decide to let him back in take it slow, and find out the root of the issues you have—maybe even see a relationship counselor. Good luck and let us know how you're doing!
