STUCK: Ms Embarrassed

Want to break up with loving boyfriend because he is too clingy, but scared to because he is lovely, I am very little savings after ex husband swindled all our joint savings/wealth in divorce, and just scared. I work and can provide for my 3 teenagers and myself. I have broken up with him 20 times, but he cries and begs me to remain with him. He gives me security and love, but his clinginess drives me crazy. And I feel guilty. Also secretly gone on a few dates when we have broken up, but never pursue them seriously because of boyfriend. Feel horrible about this and ashamed I’m so weak. Real mess and totally out of character for me. I want to move on, but keep him at arms length as scared. He deserves better, so do I. Help. Ms Embarrassed.
