There's nothing you can really because you broke up with him. But I totally was in this situation and it was so hard for me to deal with because even though I felt confident breaking up with him was the right choice... It still hurt to know he had slept with someone else even right after we slept together. The worst thing you can do is to continue to sleep with him because as much as we'd love to believe he's not sleeping with anything.... Once you break up, he's free to do whatever he wants. Stay strong and be happy that you broke up from Mr. Wrong. Mr. Right is out there somewhere!

You just have accept it and move on. It hurts and its hard but if you don't let go of it, you'll make yourself go crazy and you go through it over and over again.

Jealousy is normal, and it could mean that you're just really into this guy. Talk to him. Make your concerns known, and listen to him in return. If you really want to get back together and stay with him, you need communication. Let him know that you're jealous, and he'll appreciate your honesty.

When something like this happens, its like you thought he wouldn't want anyone else but you. When reality hits, it hurts. But honestly, communication might help. You did break up with him, and he really didn't do anything wrong. He's a guy, and this happens.
I've gone through something like this before, and he IS my everything now. We've worked it out, and it doesn't eat at me anymore since we've talked. Words can work miracles, but it doesn't work with every couple. What is meant to happen will happen.

If, however, you feel that even after communication this is a too big a weight on your shoulders, break it off. You shouldn't have to constantly feel hurt.
And DO NOT let this turn into a crazy cycle. If something like this repeats, do yourself a favor and stop it before it gets worse.

You will find Mister Right, whether it is him or someone else. I wish you the best of luck. <3

Guys sleep around, they have needs, so its normal. Honestly, you need to move on and don't sleep with him again or else it will turn into a cluster of mess of emotions. I've done the same and regret it, once I moved on and stopped sleeping with him it was easier to not care.

you get all the shit that he has bought you. go to his house, and light that shit on fire on his doorstep, covered in poop. take the jewelry and pawn it. buy you something nice. take a picture of it. place that picture in a thank you card and send it to him. seal the envelope with a kiss.

peace and love, homie..peace and looooooooooove
