I don't know if it gets better, but sometimes dogs are better companions than humans. I've always been single and I've never missed having a partner. When I look around, I see that being engaged to someone can be really exhausting. Most of the guys that've approached me in the past had weird personalities, and I didn't want to have anything to do with them.
I don't know if that's the ideal situation, because at some point you (and me) might want to create a family. The older you get, the harder it is to find a partner they say. Fortunately, there are options available for you in case you want to have kids and are still single. You can adopt or find a surrogate.
