I'm thinking of sabotaging my relationships and I don't feel guilty about it.
Why would you want to sabotage your relationship?
I hate it to be tied down into a relationship that's full of commitment. I wish to be as free as a bird.
It is fine if you want to leave a relationship, you shouldn't sabotage your relationships on purpose. You're really gonna hurt your partner's feelings.
I don't like being tied down to a relationship and having to deal with all the drama in a relationship. I'm looking for someone who can deal with me dumping them.
I might advise staying out of a relationship for the time being.  There is no sense in being dishonest or hurting anyone.
