Can I save my marriage?

[Lll54]

K so I cant get it off my mind. He came home from work last night for a snack and he apologized for his behavior before work. He gave me a hug and kissed my neck a few times. This is the first time he has kissed me in a month. I an convinced if there was another woman that it is over. But I dont think I can in on without talking about it with him. Its eating away at me. I dont think I can be with him if its true. He came home this morning from work and acted as if he was my H. Came in for a hug and commented on how I looked. I am confused. We have our sons christmas concept tonight so I dont want to ruin it but hoping someone can give me some advice on a good way to bring it up. Thank you.
