@Alwayyonthemove,
You are using women to mask your deficiencies in your personality. You're not choosing quality, you're choosing quantity, As such, the women you've brought into your life aren't healthy relationships for you and this last one turned out to be downright toxic.
Try to reflect upon yourself instead of projecting onto others your inner chaos. Find yourself and things to occupy your time other than sex with people who don't care about you. Learn a new skill, hobby or activity.
I don't know you or your likes but here's some suggestions:
-Take a cooking, bartending or creative writing class.
-Learn to sew, weld, woodworking or garden.
-Volunteer at a senior center, VFW or animal shelter.
-Join a gym, automotive club or poker/card club.
-Update your resume and use existing contacts to help find a new position.
All these things make you more of an interesting person and elevates your perception of how to interact with people of all ages and sexes.
Get out of the house without expecting to meet someone for the sole purpose of a sexual experience. You're bored and at loose ends. Find something you can connect with and explore new things. That way, your next relationship is based on something substantive, not superficial.
