I've got to the comfortable stage in a relationship now, and I dot really have many friends, I want to start going out again like I used to, and wearing nice dresses and going clubbing at stuff but I just feel too self-consious, I fel like my boyfriend enjoys the fact I have no one else and I just want to back to how I was and have fun without him, because he does without me

What do you mean he likes the fact you have no one else? Have you told him how your feeling?

Sounds like a bad relationship to me... but my advice is to do things by yourself like go to the gym, get your hair done, etc... and confidence will come, and with confidence you can leave this loser.

Balance your life with friends, and activities you enjoy without the boyfriend. Being happy with who you are, is a key in being confident, and healthy.
