<human>: Can you give me the gist of the text in a nutshell?

I'm wondering if anyone has been in a similar relationship and could provide some insight on the long term.

I met my SO 5 years ago in a chat room. It was incredibly romantic. He basically flew out to see me and I moved in with him. Probably not the safest thing at the time but he's a great guy and we got along great. We both got to know each others families and would split east coast/west coast time. I work from home and he has his own business so we can do that. We're not rich. We make ends meat and that's it. However, we've gotten into a comfortable routine.

The "issue" is we don't have a typical, romantic relationship. We have sex regularly (3x a week?) but we aren't affectionate too much otherwise. He's more so than I am but not by much. He'll hug me and we kiss each other like pecks but we live more like friends. We're great "roommates" and we care for each other very deeply. I don't want to be with anyone else and neither does he, but our close family/friends always give a weird reaction to it whenever I've mentioned it.

We don't really go on dates. We're very sweet to each other, though. We make sure to go on long walks every night and talk. Our "exciting day" is going to garage sales and finding coupons. We go to bed really early and wake up early to eat breakfast together. We're basically living as an elderly couple.

I guess my question is do you see this being a problem later? If our relationship is like this prior to marriage, will it be an issue after? Will we get tired of living like elderly people? What happens when we are an elderly couple? I mean, this all sounds weird and I'm not sure how to word it, but I guess I just want some advice on the "implications" of living like an old couple when we're still in our 20's. I do not want to break up with him, but I'm wondering if we need to try harder or restructure our relationship.
<bot>: My SO and I don't have a very affectionate relationship but we love each other very much. Is this going to cause a problem after marriage?
