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

[Snow White]

Well I think I wrecked any progress I have made last night. Yesterday was my H's day off, he was home with D4 who was sick. I have been making a point not to call because it seems like I am just checking up but since she was sick I called at around 10:15 - I had left for work at 7 and gotten no calls in my direction. My husband answered and said I'll call you back, and then I heard nothing. I called at 12:15 and there was no answer so I called again at 12:30 and the line was busy for 20 min, then when I called and it rang there was again no answer. So I decided to drive home on my lunch to check on my daughter, sure enough there they both are he is playing playstation she is playing on her leapster. I asked what was going on he said nothing, I said why have you not been answering the phone I just wanted to see how D4 was? Oh I was on my way to the bathroom when you called then I forgot to call back and then I was in the bath when you called later, I did call you at work(which he did after I had left to come home) When i asked about the phone being busy he said it was a manager from another store and looking at the call display later that person had called at just before 12:30. I went back to work and when i came home he pretended he didn't know I was there, I cleaned up the kitchen and sat down at the computer. When I pulled up the favorites it was on history instead. He came out oh I see you are checking up on me again, I said no actually you must have been in the history. Well anyways the history was on a whole slew of poems that had been written by the apparantly no longer OW. I said why did you spend your day looking at these? His answer was because I had brought them up at MC so he wanted to see what I was talking about. So I said i thought we were trying to move forward and you made today all about her again. I then ended up grilling him for most of the evening for answers again about the OW. Actually mentioning outloud I know that this is going to ruin everything I have been doing but...
Today I feel stupid and regretful and like I am forcing him in her direction even though he may have been making an effort to come back to me.
