Ho to get my Ex girlfriend back (One I truely Love)?

Awww you sound like such a sweet and nice guy! :D I wish there were more guys like you and I really hope she realizes she had a wonderful guy when she was with you! I think the stress from school was getting to her, making her feel like she needed a change, but you weren't what was needed to change. Right now it's best to be there for her, but at a distance meaning if she comes round you'll be there, but for now do not make contact. She has to realize what it is like not having you there, and I'm sure with your loving patience, she will come around.
