Don't know if it is okay to innitiate intimacy

[workinprogress]

I've been reading much about 180 behavior. My H left the first week in May. We have communicated regularly, at first there was much anger and resentment coming from him. I just let him vent, because he needed to do so. He needed to be heard and needed validation. We went to two two hour MC sessions, Gottman. But at the second one , he declared we had a good friendship and he wasn't sure he wanted to work on the marriage. He wants things to be about him. He wants to do individual counseling. I was a bit perturbed and left immediately after session was over, didn't chit chat and did not allow him to look at my directions home.
I got into an accident a couple of weeks ago, and much of our interaction has been about insurance, what car to replace etc. Last week he came to the house to get the title and mail. Prior to the meeting we had exchanged e-mails. I was concerned about the decision on the car, and whether or not I should be protecting myself, due to his not being sure about things. He responded that he was being honest and didn't want to hurt me, but wasn't sure about his desire. I wrote a rather lengthy response and was brutally honest with him. I let him know I had gone through many feelings during our 32 years. I had felt lack of desire, hate, disappointment, anger, hurt, loneliness. I also let him know all the wonderful feelings I had felt as well. I explained that I knew that feelings can last hours, days, weeks, months and even years. I let him know that I was not going to get sucked into this dark hole, that since the rolling of my vehicle I was going to choose to be happy, and celebrate my second chance at life. I also told him he needed to experience his emotions, and embrace them. He was an intelligent guy and he'd figure things out. Since that it seems as though he is much more at ease, and even a bit more light hearted.
He noticed my appearance when he came over, I've lost 25 pounds, and was eyeing me . Hung around for an hour. Now this seems odd to me, for he was concerned about not desiring me, and it was pretty obvious he was noticing me. He even told me I was looking good. This coming from a man that NEVER gives me compliments. Anyhoo, he casually asked me out for dinner or lunch this weekend, but has made no definite date on this. I am not holding my breath, but IF it comes to fruition what about intimacy? One of his bugaboos was that I didn't initiate. " I was like a church lady ". I am at a loss for if I do, and he doesn't "desire" me, have I made a huge mistake? For initiating would be a 180. I'm a bit anxious and don't really know what would be best. What if he doesn't call about going out? Do I just ignore it or do I have back up plans. I'm kinda the back up plan kinda gal. Open to input
