Why I should remain single now

I think I'm single because I need to focus on my relationship with people such my family and friends. Not that I'm taking them for granted, I feel that there's so little time to spend with them. With work and all. These past months have been so hectic. I feel that my sister needs someone to talk to with matters that my parents couldn't really relate to. I need to start playing golf again with my dad. Before his body prevents him to do so. I need to be there for my mom because I know she misses me most. As for friends, I should focus of being friends first with everyone I'm with, old or new. It's less complicated that way. And I don't need complicated right now.
