It could work for you or against you, if she has a man that she's feeling you may just push her more towards him.
I broke up with her, at the time I felt it was best because there was one issue we couldnt get over
I hit up my ex today. We hadnt talked since last April and we broke up about 20 months ago. We were texting back and forth and she seemed generally happy to hear from me, said to feel free to hit her up anytime and to not hesitate
You just let her know you still care.
