If you feel like you missed the class that taught everything you needed to know about dating and you just can’t make these things called relationships work, you may be stuck in some unhealthy romantic patterns. These default strategies can often kick in without us even knowing it — from the moment those first crushy feelings arise and take hold until the relationship inevitably crashes and burns and sometimes beyond, making it difficult to get over a guy and move on with your dating life. Ironically, the very behaviors you engage in to get into a healthy, loving, committed relationship do just the opposite, leaving you in tremendous pain and feeling like you’re destined to be alone forever. Looking back at the wreckage of your relationship history, you’ll know if it’s time to cleanse your dating palate of the chaotic and destructive patterns that have gotten you to where you are, overwhelmed by loneliness and afraid you’ll be perpetually single. Click through to see some of the biggest offenders and suggestions for how to let them go. If you can break these deadly dating patterns, you might have a shot at that love thing after all. Even though you clearly missed that day in class. I think all of us did.
