Unfortunately, no you can't. You will always question and always doubt, even when he tells the truth you will ask yourself if he is lying. It will always be the "what if" game and you will become emotionally drained. If it's not something that can be worked out (which more than likely it can't) you should evaluate everything, take some you time and make the best decision. I went through this. I stayed. And everything I tell you now was exactly how it was. Granted everyone is different, but most of the time it's a pretty spot on conclusion. Make a bucket list of all the things you love that you've stopped doing to make him and your family the epicenter of everything. When you're done making your list (ok top 5) go do them..alone..and revel in it. This will help you get through..
