T.F.
Forgive me if I missed something on that 1 very long paragraph.
How old are your 4 children?
Was the recent relationship you just ended with their bio dad or a boyfriend?
It sounds to me like you are looking to hook up again too fast with a new boyfriend, You can be a good mom and woman without a steady boyfriend. Let things fall into place at the right times vs pushing it.
Why have you already introduced him to your children? You do know it's not good for children to be involved with revolving boyfriends?
I know it's important for you to have your time and single moms do deserve free time and fun but you should have your 4 children as your priority and not worry so much about a boyfriend.
Those children will be grown up, in college and out on their own before you know it. Enjoy being mom.,, you'll have more time than you realize once the children are out of the house.
Don't try so hard to be in a relationship. Work on yourself first so you are self confident, self sufficient and provide a stable home for your children.
You were distraught in May and it's too soon to be in a serious relationship again.
