Me and my ex Gf dated for 2 yrs. I admitted to kissing a girl at a party a year ago and told her about that night. She broke down and cried as She told me that She doesn't know if she can forgive me. Continuing from this point, she started really not believing me since I broke that trust between us and from them on every time I even mentioned going to a party she would bring up that subject of me cheating. We fought a lot during the last leg of our relationship and always were yelling and screaming or just not listening to each other. She in the end stopped having sex with me and that's when I noticed a changer in her attitude towards me. Around April of this year she broke up with me and said that she didn't feel the same way about love as before. She said that there is no guareentee of friendship. And she never wants a relationship.
So basically long story short: I went into panic-mode! I sent her texts, she ignored them, I sent her messages on Facebook, she deleted me and the messages, I wrote letters, she told me to stop and leave her the F**k alone.
After all of this I tried to see her at school one time and did the begging and pleading routine- showing her how sad I was and how beta male I was. She said quote" I want to focus on my life and I need my space to figure out whats best for me. We can never have a relationship, there are plenty of guys that will treat me right"
A month later from april- may. I wrote her a letter apalogizing for the things I did, not giving her space, texting her, stalking her, invading her space in a nutshell. She responds with " Seriously stop texting and Leaving me letters. This is not the space I asked for. MOVE ON WITH YOUR LIFE and please stop contacting me" so yeah I got that about two weeks ago.
Give me your wisest advice on this situation- I have moved on and gotten myself out of depression. NO- Contact is in effect, I blocked her FB, and number, and not bothered her for 3 weeks. I just want sound advice on whether Giving her space will eventually bring us back in contact.

Sounds like she's really moving on, she's given you tonnes of messages telling you that she wants you to leave her alone and from when she said there's no guarantee in friendship it sounded as if she was trying to hint to you that she doesn't want to stay in contact with you. Once you cheat on someone they will either forgive and try to move on with the relationship and build that trust back again. But she has done the complete opposite, not even having sex with you. This shows that she has been trying to move on and this could be the best way for her, which is not to stay in contact with you.

Overall I honestly don't think you should speak to her anytime soon, when she's ready she'll speak to you. If she doesn't speak to you, don't try speaking to her because it'll hurt you when she does not respond.

Hope your moving on okay x
