While I do believe that it is important to maintain one's own self (hobbies, family, and friends) outside of a relationship, it does sound like your partner is taking that a little bit to the extreme. To be honest, my husband also enjoys quite a bit of time to himself- whether that be alone-time, time for his passion (he's a musician), or time with friends. While I don't always need quite as much space as he does, and do tend to get a little needy, I appreciate our time apart that allows us to continue to grow as individuals.

That being said, it seems that your partner may be taking this to the extreme. What do you mean he is "gone every weekend?" Is it that he likes to do something just for himself every weekend for a little bit? OR is he literally gone every weekend, all weekend? That does sound like a little much to me. But more importantly, it sounds like it is a little much to YOU! If you were ok with that arrangement, I would say, more power to you- every couple is different. But it doesn't sound as though you are ok with the situation.

I think the key to a relationship is compromise- it sounds like you are willing to give a little. Is he?
