Friends are very important. I mean men and women friends. If you guys have been together for more than two years its a possibility that you guys would like to talk about getting married. Now if you guys need more time to really get to know each other well, in my opinion I believe two years is more than enough time to meet and get to know each others parents, sisters or brothers, aunts and uncle's. Remember communication is the key to a solid realationship. So dude keep talking to her. So babygirl keep talking to him.
