Me & my boyfriend have been togeather for 7 years now we have a 4 year old son togeather.. but he has cheated on me in the past and I can't help but feel like he wants to do it again I can't trust him because all he does is lie to me about everything he says he lies so I don't get mad and upset but its worse when I find out he lies to me.. I don't understand I want us to work I love him but I don't want to be lied to and cheated on eathier.. I don't know what to do?

Have you two thought about counseling? What kind of things is he lying about. Do you question him on everything he does?

Stop getting mad and upset, and actually talk to each other. TRY IT, communications work wonders for a couple.

Are you trusting him now? Do you have a reson to not trust him now? Speaking from experience, if a person knows you are going to react badly to a situation they will lie just to avoid a confrontation. It may not mean he is lying but he is afraid that you will blow the scenario out of proportion. If you forgave him, you have to trust him and if you are unable you should go to counseling to figure out how to do that because otherwise you will push him farther away and he will lie -not based on lying about important things maybe but to avoid arguments.
