I am so confused, not sure what hand I am playing

[Snow White]

Last night was mentally tough again. H came home from work very quiet. Absolutely nothing to say, spoke only when spoken to and those answers were brief. Ate his dinner in silence and left the room while D and I ate ours 20 min later(he was having leftovers). Sat on the chair staring into space again. D was feeling sick again so we lay together on the couch. Finally after she fell asleep I put her in her own bed and went to watch tv in my room. H came in and spoke first for the first time all night, said the place that he is paying his loan off at wants post-dated cheques. I said that is not a problem - is that what has been worrying you that you didn;t want to tell me that(he sicks with money and keeps missing payments - I prefer the idea of post dated cheques). He said no, nothing is wrong. I need to go to the store do you want anything. Well I am sure I looked like I wanted to cry when I said no because he said What??? I said well pick up some pop for yourself. He said I will stop at my moms and grab some. So I looked at the clock when he left it was 7:23, at 8:15 I came out and looked at my phone, there was a text saying he had stopped for a beer and would be back at 9. I sent a text asking where - he repled, the local bar he used to be a reg at. Did I want a tea when he came home? Well I had already gone back to my room to watch tv and when I came back out to the computer about 20 min later there was 2 texts, the tea and then r u mad at me? Because I hadn't responded. So he came home at 9 with the tea, and all of a sudden was in a decent mood again, nothing spectacular but he could speak. It is hard for me not to think when he left he contacted ow and his mood prior to that had something to do with needing to talk to her.
