I completely agree with Vashti on this. In my own experiences whenever I have contacted someone or been contacted by someone of the other sex and I haven't seen them in several years, it's always started off by either flirting or there has been other intentions there aside from just staying in contact. There is a reason you want to speak that person. Whether it's because you find them attractive or whatever and after 12 years of him not being in contact of someone and now all of a sudden he wants to meet up with this girl? I would be saying Hell no! And seriously reconsidering the idea of you two moving in together only because there is a lot more you need to learn about this guy. You don't make big life decisions like that after knowing someone for only a few months.
I can't believe some of the posts on here. Everyone has their own opinion and they should not be crucified for thinking differently than someone else.
If you can't handle the thorns, don't crave the rose!!
