GMC- I hate to say it, but usually when someone asks repeatedly to give them some space (in your case, you mentioned 4X) it more than likely means that they are not sure how they feel about you. This girl seems like she means a lot to you, and that's okay, but maybe you are better off friends than lovers. If she can't handle taking your relationship to the next level after all this time, then you probably aren't meant to be together. Honestly, you are better off with someone who is more mature and who respects you. I suggest giving the two of you a break. Even though it may be hard, try not to keep in touch with her so often. Give it a few months and get out and meet new people. There are plenty of girls who are looking for good men like you.
