frustration tainted confusion

Why is it, that love and dignity always seem retractile? It's almost as if in every romantic relationship I've been in has resulted in me either choosing love over my pride, and maybe not being treated the best but not giving up entirely on someone I've cared about. Or it's the opposite, swallowing love and deciding that I don't need anyone who's going to take me for granted for one second and somehow, still ending up alone. I feel like I'm walking on eggshells and I don't know what move to make. All I know, is it shouldn't feel like this.
