It's seems like it's time to move on... I know I know we always hope for the best, but it's there screaming in your face it's over... She isn't just cheating, she's found someone new... I'm sorry... Now for you take some time to pamper yourself, take a hot bath with a nice bubble bath scent or something maybe some candles to soothe your soul... Wrap yourself in a nice fuzzy robe, and get comfortable with your favorite book or movie, and snuggle with your pet...Over the next little while you're going to need to give yourself some extra TLC, surround yourself with loved ones, and take good care of yourself...You do deserve love just not from them...

Cheaters are going to cheat. They are always going to be looking for something or someone different, better, new experiences. I know u want to be loved, but it sounds as if she's always going to choose someone else over u. Let her go. U do not need this

Who are you to forgive her? Why do you think you own her? She has her own individual rights to live her own like in this world. You are only dating and not married for you to say that she is cheating. It's your own assumption. You too go ahead and find as many partners using your free will.

Do you have any written agreement that she has agreed and signed with you that she will remain faithful only to you? If you don't want her to stray around, you should draft a contract and if she agrees and signs to submit to you as your wife, then you can say that she cannot go around with others.

If else, it is better you mind your own business and life. And don't come and paint a picture that you are a good person and call her a cheat. It is you who is a slimy cheat here trying to enslave someone and restrict their freedom. It is her choice to sleep with whoever be it just a friend or just another friend or have a ONS with anyone.

Who are you to even ask the guy even if you got to know him before her ?

reread that line:

"I don't want her to cheat again I don't know what am I doing wrong"

YOU aren't the one cheating and saying you're in a relationship and saying that the person you are dating is just a friend.

Get a better girlfriend.

If you want to be love, then it's probably a good idea to break up with the person who keeps on cheating you.It's time to face the facts.The person you think loves you doesn't.

You're young. You have a life ahead of you to be truly loved in. Leave this girl.

Well saying you guys are happy together is wrong clearly she not happy that’s why she keeps on cheating. Wake up and move on she did.

Ditch her,
