It sounds like you dated, but slid into the friend zone, and now, a few years have gone by, you’ve graduated from college, and you find yourself only two hours away, wondering what could be. I know you don’t want to risk the friendship, but you’re at the age where you may lose this opportunity if you don’t take it. Imagine if she started dating someone else and it got serious. The friendship you have with her would change. Her focus would be on her boyfriend, and you’d be someone from her past that she sees now and then. I think that it’s time to get out of the friend zone and take a risk. You may find out that the two of you really enjoy taking things to a more romantic level at this point in your lives — and if you don’t, then at least you’ll have tried. The worst thing you can do is to not give it a shot, and to have regrets. So hedge against that — and go to dinner with her, and make it romantic. See what’s there. You may find your feelings are different, as are hers. As for family match making…
try not to think about your family and her family — and just focus on what you like about her, and give it a go. You’re only two hours away now, and you’ve both grown, matured, and had some life experience under your belt. Use this potential dinner as opportunity. Meet up, show her a romantic good time, and see if there are any sparks. 😉 Seize the day!
