Quick input. She will pull away. Falling into old patterns she is. You will do something wrong. Don't follow the easy path. That little inner voice will tell you what to do. Breaking the ice is just like someone else said you gotta stick it out a little. I have laid in the bed with the same thing. After about 10 times I had to do something about it. I did not force myself/wants on her but I started to take things into my own hands. A little while later she participated. Can't say it will work for you but it was just something that worked for me. Not sure that was DB ing but. The trip to the gym was breaking the ice. When your talking see what the limits are. Its a fine line. Just because she is happier does not mean you are. You will both have to be happy or back here you will be.
