Perfect write-up. Honestly, why being in a relationship when you can't put all your 100% to the relationship. Same here, I don't believe in 50/50 but believe in 100%. And about don't love with your heart but instead your mind, sorry to say, because you were broken multiple times doesn't mean another person can't find his/her soulmate.

To make a relationship work, we have to give it our full attention because without our full attention the relationship will collapse and there's no way to work it out again because no more trust,etc.
