first of all... i know your other post and im very happy you decided to end it because you didnt sound like you were that into it.
second of all... its different for everyone. dependency is not love. love is being independent and deciding to be together still. get what i mean? dependency tears down both parties and it takes a lot to get past it. if you think that you were dependent and controlling you might look into seeing a therapist for that because chances are it wont change when your girlfriends do.
personally, i would stay single for a while until you feel okay in your independence. i always jumped back and forth between boyfriends and was never single for more than a week for about 2-3 years straight. then in september of 2005 i decided to just date around and not get into anything commited and i felt soooo much better. i felt like i wasnt myself if i was single and being single for several months straight and doing what i want was exactly what i needed. then i met my current boyfriend like 4 months later and weve been together for over 2 years and im not so clingy anymore. take some time for yourself

good luck.
