My man and just got back together after a 6 year breakup we were young back then but I loved him then and I am deeper in love with him now back then we broke up because he had anothere girlfriend. And this time it hurts so bad because my gut tell me that he is still cheating on me I just can't prove it I have clues and a little evidence but he has a lie to come back with everything I bring to him lately this has been driving me insane I can't sleep because this is on my mind really heavy its stressing me out
My question is how do I prove that he is cheating if he is so good at covering his tracks

You can't without going through a lot of changes. If you don't trust him then, how can you love him, and listen to his lies? The decision is entirely yours, as to what you do, so make a choice, is all this drama really worth it? How can you be happy when you are so uncertain?

Ok, think this through... the worst possible situation is he is cheating. In that case you are miserable, can't sleep and are stressed out. The best situation is your not sure if he is cheating so you are miserable, can't sleep and are stressed out. So move on. EIther way you deserve to be happy and not looking for evidence that he is unfaithful. You will never be happy if you don't trust him. And usually there is a reason if you feel that way. Trust your instincts.

Go wit your gut usually it's write I had a gut feeling my ex was cheating I was right just make sure your right before you do something stupid

Trust is imparative in a strong lasting relationship.

If he can't be honest then you should try to be honest for the both of you. Tell him that though you have very deep feelings for him, you can not be with someone who you do not feel is as invested into the relationship as you need him to be. Just let him know that if he is not prepared to be faithful and honest then you are not prepared to commit yourself to a fleeting romantic distraction, because that is what it will end up being.

Look luck. Trust yourself.
