A Woman's thoughts vs A Man thoughts

 Tonight, I though my husband was acting weird.
 We had plans to meet at a nice restaurant tor dinner.
I was shoppihg with my friends all dav long. so I thought he was upset at the fact that I was a bit late.
but he made no comment on it. Conversation wasn't flowing, so I suggested that we go somewhere quiet so we could talk.
He agreed but he didn't say much. I asked him what was wrong: He said. “Nothing." I asked him if it was my fault that he was upset. He said he wasn't upset. that it had nothing to do with me, and not to worrv about it.

On the way Home ,I told him that I loved Him.He smiled slightly,and kept driving.I can't explain His Behavior I dont know why he didn't say 'I love you,too.'.When we got home,I felt as if I had lost him completely,as if he wanted nothing to do with me anymore.He just sat there quietly,and watched TV.He Continued to seem distant and absent.Finally,with silence all around us,I decided to go to bed.About 15 Minutes lates ,he came to bed.But I still felt that he was distracted,and his thoughts were somewhere else.H fell asleep-cried.I don't know what to do.I'm almost sure that his thoughts are with someone else.My life isa a disaster.
