Yes, he could. I just found out I was cheated on for the last three months. If he talks about her a lot or tells you he is going out with a friend, then he could be cheating. It may even be likely. ==Maybe not, but . . . == . . . it hardly matters. He wasn't honest about not being able to have lunch with you. He didn't tell you WHY he couldn't have lunch with you, right? He made up some BS story, right? So, even if he isn't having sex with her, there is a serious level of betrayal here.
If you just happened to bump into your ex at a party or on the street and said hello then no, this is not cheating and your boyfriend lacks confidence. If you went out of your way to contact your ex then it's wrong! It is a form of cheating if you try contacting your ex. "EX" means it's over, so if you have hopes of flirting with disaster you could lose your boyfriend. Again, if you accidentally bumped into your ex then this is not cheating and tell your boyfriend to grow up!
Your boyfriend is ego maniacal and selfish! He cheated on his ex and she hit the bottom of the barrel along with him by cheating on him. This is not a way to resolve such problems. Your boyfriend has had things his way far too long and you have the power to control this situation. Talk to your boyfriend and communicate to him that you will not put up with cheating like his ex had to put up with it and if he continues you will end the relationship. If you don't ask for respect or show you are your own woman then you can't expect others to respect you. He isn't the only fish in the sea. You deserve better!
It is more likely than not.
What it boils down to is he is not ready for a commitment. What results is, if he cheated once, he has crossed a line he can never uncross and he will cross that line again. What you have to ask yourself is, "Do I want to live that life?"
She has already cheated on him once. There are a few rumors going around that she cheated on him again. But there is no proof that this is true.
This may sound harsh but if your boyfriend is cheating on you and you have evidence than you don't need to get it out of him. Just dump him! Do you really want to go out with him when he has cheated on you? If he has done it once he is going to do it over and over again. You can do better than him! Don't let him walk all over you. I hope my advice has helped. Take care.
If he isn't hanging out with you a lot.
Honesty is always the best policy. When you are alone and you know you have proof he was cheating and not secondhand gossip, tell him you know he's cheated and then it's up to you whether you want to continue on with the relationship. Think very hard about staying with your boyfriend because he may just cheat again and even if he doesn't he has broken that bond of trust you had for him.
Love hurts for especially the young where there are on and off relationships. It is important for you to realize (keep your self confidence) that he cheated because he feels like a kid in a candy shop and thought he could still be with you while cheating. Cheaters are immature; self absorbed and your boyfriend will probably cheat on the girl he is cheating with now. Cheaters will hang themselves with their own rope. Don't sit around and mope over your cheating boyfriend and realize you are loving; loyal and deserve better than him. Get out with friends; date again and you will soon find someone much better than your cheating ex boyfriend.
While cheating is hurtful to the other person and self-indulging for the person who is cheating all humans make mistakes in their lives and if they can learn from that mistake and not make it again then they become wiser. Learn from this experience and don't make the same mistake twice. Be honest with your boyfriend and if you have broken up over this then face him and apologize and then get on with your life.
Find a new boyfriend. If he did it once and you forgive him. He'll do it again and expect the same.
Leave him alone. He doesn't have to be (& he shouldn't be!) with you. He doesn't owe you anything. If you can actually be faithful, get another boyfriend & try it again. Cheating, if you want to cheat then face the consequences. Just stay single if you want to flirt like crazy; don't hurt someone because of your recklessness.
