just nothing...

how do i feel loved?. its impossible for me to think someone likes me.even though i am in a relationship. i think they like me just because they feel pitty for me. ik its like i am not trusting them. but i have my own reasons i just feel rejected most of the time. i feel inferior as if i am not of importance. even though they give me attention. its like i feel iam getting between their life. i am disturbing them. how do i get rid of this feeling?.
