In one of my earlier threads (I think it was the first one "is it over?" I described a situation when my H freaked out as I was going out. He had a nervous breakd down/melt down and I had to give him my anti anxiety medication to calm him down. I called his stepdad that seems to have some influence on him and spoke with him about the need of my H to go see a psychiatrist. He agreed and I guess talked to my H about it. At first my H seemed to be totally for going to see a specialist but after couple of days he decided that he is "not there yet" and he can take care of things himself. I pressured him a little but to no avail. Pretty much it has to be their choice to see help in order for it to be effective. I think what made a difference was the fact that I was totally open and honest about the fact that I was seeing one (psychiatrist) and he was already seeing changes in me that were good. I think it got him interested in the power of seeing a professional help. At first he was not on any meds (for the first month or so of seeing the psychiatrist) but I guess he was honest with the doctor and they came to mutual agreement that he needs to start on something.
As for ML and him saying that it feels strange - well, that's exactly how my H was behaving/reacting at the beginning. After DBing we are different people, our WAS are different as well (the mental anguish they went through changes their whole outlook on life). They need to get used to us all over again. My H was very honest about the fact that he was no attracted to me and that he did not feel anything when we had sex (we definitelly were not ML at the time of his "confusion"- it was sex only) to the point of being cruel. I started to feel the same way after a while and therefore I completely understand what he was going through but based on what's going on now I know it can pass because it did for us.
Let him experience you (maybe talk to him about his expectations and needs but also voice yours - you cannot be in the dark about what needs to be done for the M to get better - it is your opportunity as well as his to permanently fix the problems and issues) and just give him time. For some people it takes longer than for others, keep in mind that things did not get bad (before he walked away) overnight - whatever caused our WAS to become just that took time. It will take time to undo itself.
Hope that this helped a bit. Let me know if I need to be more specific.
