Totally confused

[alone]

We have been married for 30 years. He is 51 and I am 48. We have 2 children 29 and 28, 2 grandchildren 5 and 15 months. Marriage was very good until a year and half. Husband was unhappy in his job he took a temp position in same organization in another state that was to help progress his career. I stayed home since I had been with my company for 16 years and he was coming back we skyped and he was home every other weekend and I went out there. The position the came up as a permanent position and we talked again how he was unhappy at his job there that he had been with for over 25 years and we decided to move. I left my job of 17 years and left our kids and grandchild. Then after I got here the intimacy stopped in the marriage he was not able to even though we had tried a few times. We did not handle it correctly I was trying to be supportive and not push him. I should have talked more about it to him and we should have worked together on it. But besides that every thing seemed fine we had fun together and had friends. Then out of the blue I got the talk I love you and care deeply for you but do not love you that was 3 months ago. But then times he says he is closer to coming home then he is not. Then I found out about the other woman.
