Advice

I’m currently 20 weeks pregnant with my first and my husband and I are so excited! A friend of ours recently broke off their engagement and the female has always been friendly with my husband. Since the break up, she has been texting my husband more often, more so venting about her feelings because my husband and her ex are also friends. I’ve never had an issue with my husband having female friends in the past because I have always been friends with them as well, however, they talk daily sometimes multiple times a day and they have spoken on the phone as well because she said she needed his advice. I found out how much they were texting when I saw she kept texting his phone and I figured something was up. When I ask, my husband says they are just friends and she asks him for advice . Should I be worried? Am I being dramatic? Or am I not being dramatic enough?
