It really hurt because I felt like all of my efforts had been a waste. As I look back though, I don't regret it at all. It is a different story if you are just starting off a relationship being separated or if you aren't very serious about being in a relationship. I wish I could say that I ended up happily ever after with my boyfriend, but it didn't work out that way. But, that doesn't mean I am going to give up on him.
Relationships are a lot of work, but some people are worth it.
