<human>: My husband and I have been married for 4 years and together for almost 9. We have two kids together and also have my child from a previous relationship full time. He is a great partner, good father to all three kids and very kind to me, helpful around the house. In a lot of ways things are going good, but the problem is that I'm not sexually attracted to him anymore. 
Over the years since we have been married, he has put on about 50-60 pounds. Although I have had two children in the past 3 years I have managed to lose the weight and maintain my looks. However he has put on a lot of weight and does not seem to care about his looks anymore. He works from home and doesn't socialize much so he never really has a reason to get dressed, shave, or style his hair. I love him and don't want to hurt his feelings so I haven't said anything but it is starting to affect my attraction to him, and therefore our sex life. I still try to complement him because I know he feels bad, but I also know that I'm not being genuine and that comes across in how I act towards him. 

I don't want this to come across as me being shallow. I'm far from it. I don't need him to be like a fashion model or something, I just want him to put a little effort into his looks. I have tried to get him to exercise with me but he isn't into it. Although I buy very little junk food, portion control is the issue and he hasn't been able to stick to a diet long enough to make a difference. 
I'm hoping someone has advice on things I could do or say to kindly let him know what I am feeling and help him change, or just tell me to look at the good and not try to change him.

Can you give me the gist of the text in a nutshell?
