What does this mean ?

If you are still having then you are not his ex. I think you need to look at your own self esteem. You don't need this man and you certainly don't need to be doing something with him that can bring another life into the world. Stand up girl. Cut the ties once and for all. It is hard - I know from experience - but I also know that you get stronger from it. Pick people to be with who will treat you the way you want and deserve to be treated. Do not let men take advantage of you, use you and toss you away. As to contacts, I have contact with a number of ex-boyfriends even though I'm married, but I never slept with them. When you sleep with someone, things are on a whole new level. Don't sleep with someone unless you are sure they will be around (and want to be around) you and no one else and will help you if you become pregnant and not abandon you.
