<human>: Give me a shortened version of the text

As the title states I have recently lost most of my physical attraction(she still has a beautiful face and smile...) to my fiancée(we'll call her Jane).

When I met Jane I was in a relationship of 2 years. I ended that relationship within a few weeks of meeting her, and started to talk to Jane more and more. After about 3 months of talking to Jane we started dating. When Jane and I started dating she weighed around 160, she's 5'9" so her body was physically attractive to me. I was also mentally attracted to her as we hit it off, and we dated for 6+ months before anything physical happened.

When Jane and I started having sex we had it often, which was great. After a year we were still having sex as frequently as we could.

Now comes the problem.

After a few years with Jane she has increasingly gained weight. (She doesn't tell me what it is, but as far as I know she's around 190.) We have tried the gym but she refuses to attend now. She claims she has no time to attend.

I have a fairly healthy libido and could have sex once a day, perhaps more. When we first started the relationship it was the same for her.

Now after 4 years she will barely have sexual relations with me .. maybe once a month, and I feel as if sometimes I do not even want sex with her because she isn't as attractive as she used to be.

Jane is increasingly sensitive about her weight, and will not even discuss the subject with me.

With her unwillingness to communicate about her weight... and her slight gain yearly.. I have lost physical attraction to her. I do not know how to help her, or how to regain the lost attraction... I was hoping someone on here has tips/ideas to help me regain physical attraction to her... 

We are supposed to be getting married in September.. and I do not know if I am ready for that if she refuses any change in her eating habits/lifestyle... 

I feel shallow for writing this.. I just don't know how to deal with it. I've never dealt with this before.
