Dealing with an ongoing affair

[PeterV2]

We went out today and had lunch together. She said she wanted to get away for a week or two just by herself to unwind and find herself. Just stay at a cottage on a lake with a nice dock. I found that odd because she's always said that lakes are just puddles and she prefers the ocean. But last year she went to the OM's cottage which was on a lake with a nice dock. I saw the pics on her cell phone when I was snooping 6 months ago. So maybe my imagination is getting the better of me but it looks to me like she's planning a two week vacation with the OM, even though she's told me the A is over. I just don't believe her. She hasn't opened up her phone to me. I'm not about to asked her to. I just have no trust and am full of suspicion. We've been spending a lot of time together and mostly it's been good, productive and fun. Occasional heated discussions about the past and she's still blaming me for all the ills in the marriage. But she is reaching out to hug me and reaching over to kiss me. Maybe she just does want to be at a cottage alone. But I can't see her doing that because she has fears of the night. Something just doesn't seem right about it.
It drives me crazy.
