so me and this girl have been best friends/hookup, talk 24/7 and basically be in a relationship without really stating we were. She was overly in love with me and showed it a lot more than me. But we failed to communicate what we wanted from it. And as time went on we were getting a lil more serious but I failed to still treat her as a girlfriend and do things like a normal boyfriend would do in they are in love . So we spent Christmas together and everything was going great till she becam very sick and when she became sick our contact was minimal but more than ever I was very concerning and showed more affection than ever. She kept putting off seeing me and then out of blue she tells me she needs space and time to think. I pretty much confessed how I know I failed and to really give me the chance to treat her as a girlffriemd Bc she never asked me or I told I would. After telling her I would give space she blocked me on all social media so after a week of not talkin I sent flowers to her work and left a nice message . She txt me saying thank you for the flowers. So now I'm stuck Bc I have a lot of explaining to tell her reasons why I didn't take serious and stuff like that but dnt want to interrupt her space thing. So I was wondering if writing a letter of everything on my mind would be a good thing to send in mail so she can truly have all the answers to everything?
