Hi,
I feel your hurt and disappointment about your husbands behaviour. However you need to understand human nature. If two people are thrown together, working inthe same place, maybe same room, there is a natural attraction at work.
My guess is that both you and your husband are attractive people and given the chance you might have done as your husband inthe same circumstances.
The question is; does he provide for you? Does he respects you?
Regarding the sexual side, at 32 the sexdrive may be decreasing. you should tell your husband to try harder to arouse you.
