There could be a variety of reasons he's cheating. Asking him is the only way to find out. Don't stay in the relationship if this makes you uncomfortable.
If you have a girlfriend and a boyfriend, then you are cheating on both of them.
Try having sex with him...
probably because he is cheating
ok plz tel me how do you know if your boyfriend is cheating on you?
YES!!
No
Nice boyfriend.
If you can forgive your sister, you can forgive your boyfriend. It doesn't necessarily mean that you should stay with your boyfriend. Cheating is cheating and if that is not acceptable to you, you should find someone who will respect that wish.
In most cases if a boyfriend was not cheating and was accused by his girlfriend then he would be angry and since your boyfriend is silent there is a high possibility he is cheating and cannot own up to it.
dump him
No.
