<human>: Can you provide a brief rundown of the text in within 3 sentences?

I've been with my wife for 6 years, two years married. We've discussed kids and forever homes in the past, but as of late I'm getting an overwhelming feeling that if I don't decide to stay or go it'll never happen and I certainly don't want to have kids if I'm experiencing these feelings.  

I am happy in this relationship, but feel there is still a lot of room for more happiness and also feel that some things lately have driven us apart. I'm a social person and she's more a homebody; she used to want to come out with me, but now she never wants to do things with my work friends.  I catch a lot of heat now if I decide to go out with work friends and enjoy a night out, which I've done through dating, being engaged and never had problems.

 I'm a nurse and she's a teacher.  I've wanted to travel for nursing and medical missions, but it wouldn't be possible for her to go nor would I feel right going about and leaving her stuck at home while I'm out experiencing the world.  I've also talked to her about my interest in joining the military as a reservist to help pay down my student loans and have gotten a lot of backlash.  

I'm worried that I'm getting the craving to be single again(not to go date for sport),but to have no responsibilities except for my own(I know, I'm a selfish asshole).  And feel that urge growing.
<bot>: So my question is... Has anyone left a healthy, normal relationship to pursue dreams they know would not happen if they stayed in that relationship? And has it worked out?
