Maybe what your h said is true, but keep in mind, it's his perception of the situation. Then again, it could be an excuse to justify the bomb drop. You are the only one that can determine if there is any truth in the comment. BTW, my xh said the same thing and I pretzeled myself inside and out to accommodate those hugs and kisses and guess what...indifference. A lot of the comments made by them is how they feel about what transpired in their young lives and they weren't made to feel loved by someone in authority.
I'm going to suggest that you limit those hugs and kisses and see if he notices the difference in the amount he's getting. The saying around here is "do what works and if it's not working, try something different". Also, the indifference could be that he's thinking that you are only doing these things now because he said something about it...
Depression for men is entirely different than it is for women. Have you read up on anything about male depression? If not, take some time and do so. Also, I highly recommend Jed Diamond's books. They helped me a great deal. There is a Recommended Reading Material thread at the top of this Form. You may want to look at it, make a list, and go to the library and check some books out.
There could be any number of reasons why he's acting indifferent to you right now, but from what I experienced w/my xh, it was depression and his perception of his life from way back when.
Keep the focus on you and dig deeper for patience.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
