I'm hoping someone here can give me some helpful NON-JUDGEMENTAL advice.
I've been very happily married for five years and we have two beautiful young children. We have a great life together and I'm so proud of our little family. My husband and I also get on with each other's families. He has an older sister and a younger brother which is great because I'm an only child so it's great to have got two new siblings via my husband.
The problem is my sister in law, who is a really lovely lady, formed a friendship with my husband's ex-girlfriend a few months back. My sister in law was very honest and upfront about it. She didn't try to hide it or anything and was very sensitive towards mine and my husband's feelings which I greatly appreciate. I do get it: My husband's ex was his first proper girlfriend and they were together for a few years and she was pretty much a part of the family. When my sis in law had her first child, the ex was pretty much aunty to my now nephew and she definitely had a strong bond with my in-laws. But she fell in love with someone else which is why she and my husband split up and she actually went on to marry the other person although they have since divorced.
I'm not totally sure how she got back in touch with my sis in law, and it is only my sis in law that she speaks to and no one else, but I feel a little uneasy about the situation. I know that the ex is NO threat to my marriage. She's not interested in my husband nor vice versa. They haven't bumped into each other or anything like that since she started talking to my sis in law again but I do worry that that could happen, and I know it would be really awkward. There's a part of me that feels silly for having an issue with her. After all she was before my time, I have a strong marriage, I know I'm loved and supported by my in-laws, and my husband doesn't have feelings for her. I suppose no one wants the ex of partners past hanging around, and I would have just preferred it if she wasn't in our lives just as she hasn't been for several years.
How do I get over this feeling whatever it is and stop acting like the jealous wife? I really don't mean to be.
