I see so many positives, but not sure what to do next....

On Friday night H said he would come with me to get an oil change, but the shop was closed. Then I told him we needed to go to the bowling alley to pay the deposit for our son's b-day party. He said we could go right now, and we could even stay and play a few games ourselves. I said sure. We had a lot of fun, I kicked his butt. After we went home and he said he was going out now. I said okay goodbye and he left. The next day when he came late in the afternoon, he told me that he had a dream about us bowling last night. (he was with OW, but dreaming about me).

He cautiously asked me if I wanted him to move out, I said no, why would I want you to leave? Then I asked him if he wanted me to move out? He answered with a resounding NO. I said okay. Before he used to answer saying he thinks one of us should move out.

Then he said he had to go to his brothers to do some work. I asked him if he was going out at night again. He said maybe, I told him to tell me yes or no? He said yes, I said fine, then I guess I won't see you till tommorow. He said that's not true, that he would come back home when he finished at his brothers. I said why? You mean you will just come home to get ready to go out right? Well I am not going to be here so I guess I will see you tommorow. He looked a bit upset, then left. I wasn't going to wait around to spend 10 minutes with him while he got ready to go out with OW. So I went out. He called me later on my cell and said that he would spend Sunday afternoon with me, and that he would be home early. I said sure.

On Sunday, he was late. I was pissed, but I tried not to yell at him. He was very apologetic, said he slept in, as soon as he got up he left and was worried about me being angry. We spent a really nice day together, he told me that everytime he is with me, he is so torn inside. We spend the whole evening together too, it was nice. He said he was thinking about ML with me all night. (he was with OW, but thinking of ML with me)

I feel like we are so much closer now, he doesn't seem like he is desperate to leave our R anymore.

Positives

He is starting to realize that he does have strong feelings for me, that he won't be happy if we are apart - this took him by surprise.
He is thinking about me when he is with her.
He says he loves coming home from work to me.
He says that I look so amazing and I am the 'ideal woman'.

negatives

He still goes out with OW, constantly talks to her.
He is still indecisive about us. He still mentions me moving on.

I think the scales have tipped more in my favour. I know that if I had told him to move out a few months ago, he wouldn't have gotten the chance to see how fun and good things could be with me. He wouldn't be questioning his decision to leave me for OW like he is now.

I think I will continue to DB for a few more weeks. Hopefully he will continue to get closer to me. Once I see more improvements, should I tell him that he needs to make a decision - that he can't continue to cake eat?? I know
that if things continue to improve, he will most likely choose me if he is forced to make a decision.
However, I don't want him to resent me, so I don't want to rush things, and make him decide before he is ready. But I don't want this limbo to go on forever either...

Of course I wouldn't phrase it like an ultimatum or anything, I would just say that I can't continue to be with him as a wife while he is continuing to see OW. That it is too painful for me etc... I will be changing my behaviour, not telling him to change his. This will of course lead to him having to live without me as his wife and could force him to make a decision. What do you think????
