My husband is really trying me right now... every other night that he hasn’t worked late he’s been going out & seeing his friend not coming home til 12 or 1. But is “too sick” to do anything with his family outside of the house. We haven’t been intimate in how long & he only kisses/ touches me if he wants something. He was telling me he had to go out of town for work training and stay in a hotel & now all of a sudden his job is sponsoring some kind of dinner at a restaurant tonight he’s telling me about. And because I responded “Oh ok” he wants to go off and start an argument & catch an attitude. I’m really just starting to get over this shit.....
