Eh, just a point:
If you live with each other long enough (in Canada it's a year), the law basically sees you as BEING married, anyways, and the other person has the right to 50% of your stuff. It's called "Common-law partner" up over here.
I dated a girl for 2 years. We were pretty happy living together. Then she decided to head away for a Master's degree at a university that was 2.5 hours up the road. I had a full-time job that i couldn't leave, so we tried to do the long distance relationship thing for awhile. We got along very well, but i was sacrificing an awful lot for the relationship (every weekend i was driving up to see her, so i basically had no life outside of work and her). She then took a job that was another half hour up the road (so it was a 3 hour drive now!)
I tried to find work up there, but there was nothing. I was literally weeks away from breaking things off with her when she told me she was knocked up. We were at an impasse. She didn't want to move back to the area where i worked, i couldn't in good sense leave my job (it was a very good job in a field that was tough to get into, and now that i may have a child on the way, the benefits package i had was more important then ever!) ..There was alot of soul-searching and discussion done on whether we were gonna try to make this work or no.
I finally decided to commit to trying to make it work, but after everything that had gone between us, all the uncertainty....How do you really let each other know that it's not just talking lips and words?
I proposed to her. And her complete emotional breakdown that night told me all i needed to know about how important the vow of marriage was. She's not even religious, a complete atheist.
