Why I feel exhausted with my relationship

You answered you're question already, when you feel bored and tired then there's something wrong in your relationship with someone. Maybe because there's no fire anymore just give each others time to be free so you'd missed each other.

Take a break, as peter cetera said "even lovers need a holiday, faraway from the one that I love" so you have to do exactly that. There are times that it seem that our relationship is already choking us. So go away and think things over. More often, people need to spend time alone to evaluate things up. When you alone, weigh the negative and positive in your relationship, if the negative outweighs the positive then it's time to part ways. Life is too short to stick it to a relationship that is no longer working. Cheers!

well, raini you answered you question already, if you are exhausted or bored with your partner cause he/she's burden to you it's really not a nice relation to, did you talk to him/her about you issue? if yes and still you feel the same, it's about time to end and move on..
