If the boyfriend's slimming action has been going on for some time, but there is a problem in your's relationship, it is time to fundamentally solve the problem. First of all, we need to determine whether slimming is the only reason for breaking up. If there are other problems, we need to solve them together. If the breakup is really caused by slimming, we need to support and understand our boyfriend and tell him that you still love him both inside and outside.
Besides, we can try some romantic ways to save our boyfriends. For example, you can cook a special dinner for him or go to the movies together. This will make your boyfriend feel your care and love, and then slowly come back to you.
Finally, we need to remember that love needs mutual support and understanding. If you really love him, then you should give him enough support and understanding to help him overcome the problem of slimming and finish every journey of his life.
