maelia8, at least you should try to make strong relationships.
I was dating a grad student, who I met at kovla site. We also had to decide to study hard or to spend more time for dating.
I straightly asked him about our future. Luckilly, we had the same views for it. We are still together and we will get married soon. Do not be afraid!
For me, it was quite rather difficult to date. Coz I almost had no free time and needed person.
The only one way for me was online dating services, like kovla and others.
