I don’t know what to do anymore.

Ive been with this girl for practically 6 years. The first 2 years we were bestfriends. The 3rd year i told her that i loved her, cause i felt like i really needed too bc i truly love her. Well everything was literally perfect. Until, this guy from my past tried to contact me and my stupid ass talked to him and i cheated.. she forgave me which i couldnt be more thankful that she did. Well, almost a year and so many months have past and nothing is the same. She wont let me come to her house, she wont spend time with me unless its literally convienant for her. I sent her paragraphs upon paragraphs telling her i love her and how i felt about her and i dont get nothing back. I try to get her to stay with me all night and she wont and im getting to the point where im done with it. Idk what to do anymore. Help me.

You slept with someone else. Cheated. She said she forgave you, but by the sounds of it she didn't. Now she is getting more and more. Perhaps it is time to move on. And the next time you 'literally love someone' don't cheat on them.

Sounds as though she has tried to forgive you. But the trust was broken. it’s one of the major factors in a caring relationship. Once broken is too difficult to mend .. if ever. You should move on and allow her to move on as well.
