Can I save my marriage?

[Lll54]

K so went to drop off S3 and stayed a bit to visit with FIL and SIL. H stared at me the whole time! Then when I was leaving I asked if I could leave my truck in the driveway. And it began. He got so upset. Why you leaving your truck here? Where are you going? Who are you going with? I said to the mall. That was it. With my sis and she asks of if H knows this guy that she knows. So I text him and ask. He says no but should I? I said no just wondering. He then asked how that came up. I said in conversation just to spark his curiosity. He says oh ok. Nothing for a few minutes then I get another one asking if everything is okay. Um since when do you care and why are you asking? Told him Im fine. He takes it offensively. I apologize if I sounde rude and re stated that everything is good and now he hasnt responded. Now what?
