Daughter getting married and need to look H OT -

Signal2020

I joined this site a while ago and just came back after seeing a commercial. I was married for 22 yrs before being traded in for a 21 yr old. I went on the "divorce diet" and lost over 100 lbs. I met my current husband a couple years later and slowly about 40 of those lbs have come back. I need to get back into shape and drop these lbs.
I am discussed with the way I look and it is affecting my new marriage because I don't want him to touch my FAT! He tells me I am the bomb, but no man likes to grab fat.
Our daughter who is the same age as my ex's girlfriend gets married in May and I would love to find an amazing dress to walk into that wedding -- but I can't have an amazing dress until I get back into shape.
All the support, recipes and encouragement would be wonderful. I am great at eating healthy, but I HATE exercising and find it hard in my schedule to get it done. Any suggestions on exercising for those who hate the thought and don't have 90 minutes a day? NOTE: I injured my knee in a car accident so a lot of exercises really hurt the knee --
suggestions --
Thank you!!!
