Can I save my marriage?

[Lll54]

I cant say anything like that cause it obviously came from my sisters mouth and she told me to swear I wouldnt say anything as she doesnt want to be involved. I left this morning and on my way out he complimented me. How much he likes my jacket and how good it looks on me. I was still so mad that I said thanks and left. He is on nights now at work so I am just trying to stay away till I have a good chance to sit down and talk to him.
