My boyfriend says I am fat!

I have been in a relationship for two years and my partner has not been physically intimate with me lately. I used to brush this off as a mood swing until he told me it was my weight that was bothering him. He says I used to be slim and the change in my figure is putting him off intimacy. Could this be the real reason? Should I try and lose weight to make him happy even if I don’t see a problem with the way I look? I love him and want to be with him, but this comment has been hurtful even though I know he is being honest with me. How do I react?
People change over time, and our bodies aren’t meant to stay the same. Relationships evolve too, and ones that last are built on mutual respect, love, and acceptance. To avoid intimacy because someone’s body has changed is a sign that this isn’t someone prepared to go the distance. You may love him, and he may reciprocate, but long-term relationships depend upon the ability of both partners to acknowledge and accept that they will change in multiple ways. Do you want to be with someone who wants you to change, even if you are happy the way you are? You may be able to lose weight today, but for how long will you be prepared to try and maintain something you have little control over as the years pass? An honest answer to this question may help you evaluate where things stand and what you are signing up for by continuing to be with this person.

Is it normal to be in a relationship with someone I don’t want to be with just because I can’t imagine him with anyone else?
That depends on how much you are willing to compromise, and to what end. If you don’t want to be with this person, and your reasons aren’t good for your mental or physical well-being, what do you hope to accomplish?
