Ex husbands new girlfriend saying "Love you lots" to our DS

[Jumpinginwithbothfeet]

My ex husband has a new girlfriend of around 3 months. This is one of many girlfriends since we split. He took it upon himself to introduce her to DS 12 on his weekend. She now has his mobile number also and has messaged him (about his dad etc I am keeping an eye on messages). I overheard a phone call with DS, his dad and her and at the end of the call she said "Bye, love you lots" to our DS. AIBU or is that just a bit weird

It's a little OTT but it's just a gushy turn of phrase. I think I accidentally said to to a senior at work by mistake?
It's not really her fault he's got a revolving door of girlfriends. She maybe is just trying to make an effort. If your monitoring their calls etc then you'd know if she was really overstepping.
Of course if you don't want him to have her number you can ask/demand he stops correspondence.
It may not last but if it does at least she's showing an interest in the kid from quite early on.
Do you know if she's got kids?

Yes she has a daughter as well.

I would speak with your ds about the new relationship so that he knows he can talk to you about it if he wants to. There's nothing you can do to change your ex's behaviour or his gf, but you can make sure your ds can talk to you about how he feels about it all. That will also allow you to hear about anything concerning early so that you can take action if needed. I don't think what she said is concerning in itself but yes it is weird her saying that and must have been unsettling for you to hear it.

She'll be calling herself your ex's partner and that she is a step mum. It must be awful to watch knowing she'll be simply another in a long line.
