by asking your best friend to spy on him
Well that is kind of like asking is a girl can have more than one boyfriend. If she did people would call that cheating. So if you think that cheating is right than sure you could be if you don't than no.
Maybe they are just friends.Try asking him about it , but don't make it seem like he might be cheating
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.
Take a picture of your boyfriend along with you because he could have well used another name at the motel. Give the clerk your boyfriend's name first and what date he would have been registered at the Motel 6 first to see if he did sign in under his own name and if not then show the picture of your boyfriend to see if the clerk recognizes him having been there. Some clerks may not give out this information or, if you give them $20 they may be willing to bend the rules and give you the information you are asking for. If this does not work and since you are suspicious that your boyfriend is cheating then you have an idea that it probably on a weekend he is doing this and you could get a girlfriend one night and secretly follow your boyfriend catching him in the act.
Read that question back to yourself and then ask yourself why you would be with someone who you can see cheating on you and that you believe will lie to you...
If your boyfriend calls all his female friends "babe" it is highly unlikely he is cheating on you. Even so, you are better off asking him directly and see what he has to say.
As i am a boy myself i reckon i wouldent like to be accused of cheating until you are certain they have cheated but if you have that proof best to just go up to him and ask not in a loud vioce but a quiet one
When he starts asking where you were? When he constantly texts or calls you and gets mad when you dont reply right away or answer. Or when he starts wondering who your hangiing with.
It depends on how many times he asks you. Maybe he is being too cautious, or maybe he is cheating, or perhaps he can't bear to think you are cheating because he loves you.
Be very sure you have some good reasons to think your boyfriend is cheating. If you feel he is (called 'gut feelings') then go with a girlfriend and follow him on the weekend. You can also ask around. Try asking his friends, your friends or anyone else he knows. If you think he'll admit to cheating most generally don't. Catch him in the act.
i would start by asking your boyfriend.
