Re: help me_how to achieve it
I'm sorry to have to say this, but the truth is this man does not care about you and does not respect you. People who care about you do not use you as if you were nothing more than a warm hunk of meat. And they do not take advantage of you when you are feeling down and vunerable.
The first thing you need to do is to never see this man again. Cut him out of your life completely. And learn from your mistakes. Now you know that having sex with someone who you are not in love with, who doesn't love you, who you are not in an honest, commited relationship with is not for you. Some women can do it just fine, some can't, and that's fine. You are one of those women who can't. Now that you know this about yourself, you know to never again have sex with a man who has not declared his love for you and who has not commited to you in some real way.
In the meantime, get back to your life. Work, hobbies, passions, exercise, friends, family, surround yourself with things, activities and people you love and enjoy. Chalk it up to lessons learned, we all have them, and move on. Good luck.
