RE: "The spark has gone. Since I gained weight my boyfriend doesn't want to sleep with me. How can we solve our relationship problems?"

Women: I lost weight, and men started paying way more attention to me, and I felt like a sexual object, and it was terrible.

It's no wonder we don't understand each other as well as ourselves. As @nomad-magus says that we need to regain the trust within our self and reconnect with the source that loves us and nourishes all the time is absolutely true.

Lose weight to feel good about yourself, to show your love for yourself. You will MUCH more confident and have a healthy amount of self-confidence. I lost 8 Kgs in last two months and not only do I just look better, I am better. I'm better physically because I can actually do just about whatever I want, before I could barely walk down the road without getting tired. And since I feel so good about myself, the days are spent very well and happily.
