Is it personal preference

So I love being a mum and going on adventures with my boys, but being honest I do get those times where I would like 5 minutes to myself (occasionally). I do have a partner but he is always working (no work life balance) so I am doing all the parenting again I don’t care majority of time . Just recently, I got back in touch with a friend and she suggested going for an evening meal with her and another friend she has kept in contact with. She asked me what days works -so said after 5 in week but we can try do a weekend , not left my boys as I do the bedtime etc (I didn’t make a big deal just one little sentence). She comes back with oh forget that- we both finish at 5 so let’s do a weekend - you need a partner like mine who is ace with bedtimes and having kids when I go away- you need you time . I don’t know if it’s just me reading into it, but it kind of annoyed me; like surely it’s just personal preference if you want to go out and leave kids or have you time? Like I said I like doing things with kids , life is busy and only on odd occasion wish I could have 5 minutes me time - is this bad?
