I'm busy these days, no time for my girlfriend!

I think you can just call her to tell her you care for her,or you can sent an e-mail or message to her.That's quite effection.

Hello. I understand your side. It is really difficult. I can imagine. Just use the high tech world of ours into communication like mobile phone in just saying hi and hello. At least, she knows that you still exist. And use time management into your schedule. Goodluck.

You have 24 hours a day, how unfair of you not to create just 1 hour of your time with her? Please dont break her heart, dont make her have unfounded ideas, dont torment her, give her some space within your crowded schedules, it will make all the difference

Hi coolfish85, However busy you are, in this technologically advanced world you could have at least talked with her by phone. Why you din't do this. Naturally if one absents himself without intimating others, they get all kind of doubts. Convince her, pacify her and if necessary convey your apology to her. Good Luck
