My H does the same thing...one minute he is kissing me and hugging me and telling me I look great, the next he is giving me the cold shoulder and flaunting OW in my face. He was mad at me for a few days this week...acting very distant when around and giving me very short answers to questions. I asked him what was wrong and he just said he was having a bad day. Then he asked me if I left an earring at his apartment. I didn't, but it sounded like a good idea I have a feeling OW found it and was mad...he probably thought I planted it there last time I was over. He seems to think my mind works the way his does...always looking for a way to get revenge.
I just wish he would dump the little girl and get back to real life and responsibilities of raising our family together, but it doesn't look like that is going to happen any time soon. Haven't really heard from him much this week...I've been crying a lot. Part of it is because Mother's Day is coming up and I miss my mom. She died this time last year and I've really had no emotional support from him at all.
Sorry to ramble on about my own woes. Hopefully we'll have a better day tomorrow.
