Relationships... especially healthy ones.. are so damn difficult. You have to always be compassionate, empathetic, selfless, loving, caring, understanding, open, honest... the list goes on...if you awnt it to work, of course.
Don't get me wrong, the benefits are well worth it, but what about those insecurities that pop up? He's going to find someone prettier, more religious/non religious (depending on preference), more outgoing, more playful, better with kids--whatever!
It all really comes down to self-love. Knowing that if you are with the person you want to be in a partnership with (truly the person you need in your life) then they will accept your insecurities, your hurts, your flaws, your downfalls and help to lift you. You will need to lift yourself as well, but we humans can't be strong 100% of the time. That's why I personally feel that relationships are something magical. When you are weak, they are strong.. so to speak.
In the meantime, working through the parts that are difficult can be no fun, but lead to greater understanding and love later. Things like--expressing emotions that you consider negative. Telling secrets you swore to yourself you'd never tell a soul. Admitting when you're wrong. Conceding when there's no agreement in sight or just agreeing to disagree...you know the stuff the ego wants to hold on to.
I was just thinking about how my boyfriend and I work through issues, but of course new issues will always arise and that's just part of an ever evolving relationship and being in a monogamous long term relationship to boot. My boyfriend himself has never been in a very long relationship, whereas I have been in a 6 year relationship and haven't had this much communication with anyone, let alone my ex of 6 years. It's exciting, scary, daunting, fun...all the scope of the human emotions. I can't wait to see how it goes. :)
