I am in the early stages of a relationship, and everything is going great. But, a former co-worker has decided that myself and her have “dated”, and messaged my new girl saying that we were still dating, so look out. It has dealt a pretty serious blow to our relationship, and we are looking to repair it. My current girlfriend worked with her in a networking group and may have slighted the girl that is trying to wedge into our relationship.
What would be the best way to handle this? We have thought of inviting this person out to call them to task, or to message her back, but I’m thinking this is just giving our relationship power, to her. On the flip side, we thought about just ignoring it and not giving it any energy. Thoughts?

Go to Human Resources and report her stalking. Make sure to log every thing she does and if you feel like you need to go to the police. Just because she’s female doesn’t give her the right to stalk or harass you.
Did she date you? Never fish off the company dock my friend. Just block her on social media and report her to HR if she does anything else.
