Just wanted to share my story which is similar to yours a bit my mom dated a man who never had children and honestly didn’t understand the dynamic I actually lived with my mom and her partner who from the moment he moved in wanted my mom to himself and made it very aware he has never wanted children however that did change unfortunately down to my mothers age never happened.
There was me the eldest and my younger sister and brother from the moment he moved in it was a very much a him and us vibe instead of my mom taking us to school I would have to and this man didn’t want my mom getting out of bed before a certain time over time the relationship got worse and unfortunately did turn abusive he did end up hitting my mom and she did throw him out only to have him back a few days later. This became a pattern.
They are still very much together almost ten years later and I honestly pity her I’m currently 8 months pregnant with my first child her first grandson she had made comments about babysitting and her partner has made comments about it being there chance to be parents
and constantly calls my baby there son it’s very strained when I’m alone with the partner although nice to each other I don’t trust him as far as I could throw him he too struggles with social engagements and that’s very apparent with family get togethers.I know I couldn’t trust the partner alone with my child and I end up feeling sick knowing my baby would be in his presence and because of that my son may potentially lose out on memories with his nan. In turn she will lose out on time with her grandson as the relationship has become strained due to her relationship with the partner.
i don’t want to upset you just wanted to give you a possible glimpse in the future I have no doubt your daughter is aware of how your partner feels even if she doesn’t voice it to keep the peace and maybe she will have a baby one day too I just hope she doesn’t feel like I do now where you know there’s no way of fixing things I do hope you keep the strong relationship and I have no doubt you love your daughter.
