She doesn't like you because your man jigglers are the size of Donald Trumps jigglers... You should know that
Leave her alone. Nothing you do will change how she feels, and if she told you she's not interested, you have to respect that.
Her feelings may change, but if she doesn't like you now then you should move on. Unless you are assuming how she feels and didn't ask, in which case you can either ask or definitely move on. If you try to guess how she feels, you don't really know her.
True. Also, don't try and make her feel sorry ry for you and put on the spot to 'love you' back from pity.
Separate yourself from her and all things that remind you of her. Work on yourself... Your hobbies... your goals... things that make you better independently. You may seek advice, but try not to take advice from too many people in failed relationships or who don't have much relationship experience in the first place. I can assure you that you will find a lot of inexperience here in the forums. Find people with a much relationship experience and especially successful relationship experience. Talk to those people about coping with the heartache and how to build stronger connections to the point where you can completely be yourself and find and keep a person who loves you for you.
