AIBU red flag grandparent behaviour

Hi

im not sure if I’m being unreasonable or not. please don’t be rude as im genuinely not sure and I’m open to opinions.

( it’s worth saying I’m a SA survivor and have had a tonne of therapy to live without this affecting me but it still crops up from time to time. )

for context:

when I met my in-laws within a week I knew something was up with FIL. I had a bad feeling he was being unfaithful from his behaviour and we all found out a few months after that he was for years. I didn’t trust my gut and didn’t say anything as I was new to the relationship and didn’t know him.

We are now on holiday and I’ve had a niggling knot about how he treats my DD, 18mnths, it’s very self serving, all about him and not her and he says things to gain a cheap laugh rather than connect with her. I’ve been commenting on this to support my daughter in a discrete and daughter-affirming way, I’ve not been horrible but kindly and firmly responded to try and put some boundaries in. There has been a visible shift in how he looks at me to be quite cold now (which I don’t care about but feels very telling).

tonight in front of a group of family he asked her unprovoked to lift her top up to show him her tummy multiple times with no relevance to the conversation and unprovoked. He then proceeded to get her to lift her top up by lifting his own top and showing her his full belly. This had set off a huge knot in my stomach, and that feels like a huge red flag to me if the other things weren’t already. I feel it’s a clear boundary that a grandad shouldn’t show his granddaughter his stomach or any other under clothes body part? Especially as a bribe to see hers?

my husband has spoken to him and said don’t do it again we don’t want her to learn it’s ok to show people parts of her body just because she’s asked to. He apologised.

there is just this massive warning flashing in my body that he isn’t safe to be around. I can’t tell if I’m overreacting or if this is actually really weird behaviour. AIBU?

How close is your DH to his father? I would never let my DD near this man without being present myself, and even then, I would not foster a relationship for her with him. Even if he isn't going to abuse her, he is being wildly inappropriate and lacks good judgment.

he idolised him before the cheating came out, but his family have kind of swept it under the rug, are still together etc, so it’s easy for them to ignore. Him and MIL have babysat once for our 12 week scan for second child and we asked for only mil to change nappies for that. they have offered to have her for the rest of our scans and labour. They only come over once or twice a month and she isn’t alone with them at all. But yeah I am glad that it’s not just me who sees that as red flag behaviour in a general sense.

Well that could be completely innocent. Or not. Totally understand why it's setting off alarm bells for you though.

That’s really affirming and making me feel less guilty about my reaction. Thank you. My body is really saying he’s not a safe person but I feel like if I’m wrong then that’s a terrible thing to think. I’m finding it to be a really hard situation to navigate

I wouldn't want my daughter anywhere near him. Is your partner your child's father?

Yes he is. He said that she’s our daughter and we need to come up with a plan moving forward as he trusts my gut. I’m worried im overreacting but also don’t want to take that risk, hence mumsnet
