I second jgnat's recommendation to see a school counselor about your depression and getting help to deal with this present issue.
As a former JW, I can tell you that JWs date non-JWs. But, the catch is that they have to convert them to JW in order to get married in the Kingdom Hall. There are alot of sermons (i.e. "talks") made at various JW meetings about the spiritual perils of not marrying a JW. The two would be unevenly yoked. You see, JWs strongly believe that their religion is the only good religion on this planet that is blessed by God. They think that God has/will curse/kill all others (and all non-JWs) at Armegheddon. Simply put, God will kill a non JW wife & non JW kids at Armegheddon. They will be dead forever. It is not "rational" for a JW to get invovled with a non-JW. But, JWs do do alot of preaching and trying to convert. That's basically supposed to be their sole interaction wtih non-JW people
As far as college, JWs don't really tout college. It is lightly discouraged in their publications and open, Sunday meetings. But, when you go to a more hard-core convention (say, a Friday or Saturday session that the public usually doesn't attend), you will see how much college is discouraged. It's discouraged, officially, because a college education is worthless since God is going to soon destroy this world. What good is a profession? . . . has been the question for about 100 years. So, even if you got married to him and had kids, he sounds like he is against college. He wouldn't want his kids to go to college, and he probably isn't going to be "supportive" of any of their non-JW aspirations. This ranges to holiday celebrations, sports teams, honor societies, school clubs, debate teams, birthday parties, Boy/Girl Scouts, etc. All are off the list for children of JWs. And, since he will, technically, be the head of the household, he could get emotionally (and alot of JW men are physically violent) with you if you don't obey and allow the kids to join in such Satan inspired events.
Now, if he can get your/his kids to join him in the JWism life, he will probably get them to write you letters begging 'mom' to come to the "Truth" becuase the kids don't want to see her die at Armegheddon.....
Your life wasn't crazy before he came into it. He (and his religion) are the common denominator.
I think what you probably liked about this guy is that he was a spiritual person. That doesn't mean that there are not other guys out there that are spiritual. And, I bet you can find one that doesn't belong to a radical, doomsday cult. Go to one of those mega churches. They probably have a singles night, where young folk can mingle together. Get back out there. And, get to a school counselor.
