SUBREDDIT: r/relationship_advice
TITLE: Could use some insight. Never asked for relationship advice before.
POST: I'm 30 years old and have been with my girlfriend (lets call her Jane) for about 5 months now. She likes me much more than I like her. In fact, she's in love with me. We don't have a lot in common and our intelligence levels are separated by a wide margin, still, she is an awesome person and has her crap together better than anyone her age (she is 26). The last 2 women I was with, were beautiful and I fell in love with them relatively quickly. There was an overwhelming "WOW" factor with them. But I put so much time and effort into those two relationships only to have them backfire and end in heartache so I vowed to focus on myself and do the things I want and need to do. I  believe Jane balances me out and could be a great partner to have in life but there just isn't that "WOW". I know if I broke it off with her, she would be really hurt and I would also lose a potential asset to my life. Should I just back off for a bit to see if I develop stronger feelings or just cut ties before I get deeper into something that I may not really want? Again, logically, she is a great addition to my life but emotionally, I feel withdrawn. Any advice is greatly appreciated.
TL;DR: 
Girlfriend of 5 months wants more than I do and is falling in love quickly. Could potentially be someone who keeps my life in order but I lack the emotional connection she has developed.
