Being a semi-stepmum (my partner and I don’t live together) has destroyed my mental health. When you ask what causes the feeling of resentment towards an innocent child, in my case it has been a symptom of trauma caused by the challenges of dating a man with kids. My partner has 2 under 10. I have one. I had an amicable divorce, my ex and I are a team and my ex’s girlfriend is lovely and occasionally will help out with childcare in emergencies, for which I will buy her gifts. I’ve supported my son’s relationship with this kind woman. My son is really trusting and friendly with my partner.
On to DP: we got together when he was in a horrible court battle for child access. Him and his ex accused each other of being unfit parents. After every hearing he was in a very dark place. Suicidal at one point. I was his only source of psychological support. My DP’s kids are very damaged. One has attacked me and my child. The other tells me constantly ‘you’re not my mum.’ Both have significant behaviour problems. The ex wife appears to hate me too. If we’re ever in the same place she refuses to say hello, and as she’s a really sociable extroverted person, her ignoring me has the effect of modelling to her children that I really don’t matter. She’ll also change child arrangements on a whim, but refuses to be flexible herself, which has disrupted time DP and me spend together and ensured we can’t take all our kids on holiday eg when we asked for an extra afternoon on an Xmas handover day, which would have enabled us to take them abroad for 4 days of winter sun.
After 2 years of DP’s court hell, kids who resent my existence because I’m the living proof their parents will never get back together and undermining from the exw, I’m an anxious, depresssed mess. I’ve gained weight, I binge eat and drink, I’m on citalopram, I shout at my own kid for the first time ever and as someone who works as a childcare professional I am deeply ashamed about this, and also that I couldn’t deal with my DP’s kids better (tbf they also hit and rage at their own parents).
I started seeing a therapist who said I’m traumatised. A factor of trauma is being constantly on guard. That includes intense fear ahead of any ‘blended’ (haha) ‘family’ (lol) experience. When I visit my DP and his kids I don’t feel safe. I don’t know whether this will be a day the kids decide to be nice to me or how long any nice times will last (because the exw alienates me, if the kids do bond with me they feel guilty they have let their mum down so any period of niceness and calm is followed by angry rejection).
My DP is no Disney Dad who keeps me around for doing chores and free childcare. He has a good job, a cleaner and a nanny. He treats me like a goddess. He understands. He pays for my therapy. He moves to protect me when one of the kids is awful to me or ignores me. He puts photos of ‘all of us’ in his house and of us as a couple to show his kids me and him are a unit. He’s taken all my suggestions to help his kids behaviour on board (martial arts for the sometimes violent one, therapy for both). But sadly I am often finding myself angry with him too. I have absolutely no capacity to be treated badly by exw or kids anymore. One ‘small’ thing happens - a schedule change by exw that I know she will rant and scream at DP about if he doesn’t agree, another snide comment from s child, and because this is the 1000-th time it happened I will rage and cry. I don’t know who or what I’ve become. There was an alienating comment from one of the kids a few weeks ago (just the one) and I ended up curled up in a ball on the bathroom floor sobbing quietly to myself.
So while I can’t give you any answers OP I’m here with buckets of empathy.
One thing my very kind DP has agreed on is that if I want to go to very minimal contact with his kids I can. This means only seeing them once a month or so for short periods. They will not feel I’ve abandoned them (at some level they may have an attachment to me) but also will not get to use me as a target for their anger. I will not have to witness their behaviour problems. If there is ex wife drama my DP will talk to his friends and therapist about it, not to me. My DP will use his financial resources to get them more help. He is happy to accept that his life is complex and hard and that none of it is my circus.
Since we had that conversation I’m starting to feel some hope for myself. I feel in part like I’m going to become a cold, heartless woman who no longer supports the DP with all his troubles. But if I don’t put this life jacket on now I will drown and take my own child with me.
