I’ve been there and know how hard this is. My suggestion is to give her space and to start dating new people, as hard as it might be. Chasing after her only makes you look desperate and needy and that turns women off. She needs to miss you and if you’re always around calling, texting, emailing, trying to see her or whatever she’s never going to feel what it would be like to lose you. Also, if she really wants to be with you in the future she’s not going to want to risk losing you by having you date other people. If she doesn’t care, she doesn’t care — and you need to move on. 😉
