BD asked me to go to the beach with him and our son

He asked me if I want to go on vacation with him. Honestly I’m not sure what to say.🤣

I don’t know if his girlfriend is going with him, he didn’t say and either way I just feel like I’d be uncomfortable the whole time? Our son is 3 and this would be his first beach trip and I’m sure he asked me to come because 1. We’re not quite there yet in our co parenting for him to take our son and go off hours away for a week or so by himself. 2. It’s his first beach trip and he would want me to be able to experience that too.

I said I’d think about it but I’m just not sure. I feel liked it’d be awkward.
