I don't think that you can really choose who you fall in love with (just look at my exes). However, you can very much be in love with the wrong person for you.
All successful relationships require some sort of compromise, but do you think you're putting more of yourself into the relationship than your partner?
When it comes to finding the right person in your life, don't you always feel like there are "signs" out there saying whether or not the person you're seeing is "the one"... or not?
Whether your relationship is brand new, or you've been dating for a while, there is some give-and-take that all relationships should have, and it is healthy when both partners take their turns.
Whether you're in the beginning stages of a relationship, or you're two years in and thinking about marriage, there are some things that you and your partner should enjoy doing together as a good marker to see if they are "the One".
The saying goes "how can you expect someone to love you if you don't love yourself". While true, how also can someone really get to know you before you even know yourself, too.
