Hi,

Just want to add this, in some part you mention that these are not big issues at all. The fact that these lifestyle differences are making you reconsider a serious relationship makes them big issues. However, as the other response mentioned as well, I believe, when in a relationship, one should let go of the ideals. yes there are certain criteria and it seems your guy matches those. The chances are none of us will meet somebody that has exactly our ideals, however someone that satisfies our criteria might be actually the ideal person,

Hope you make a decision that makes you and him happy down the road
