All the time I hear on here that mums should never introduce any man to their kids until they are absolutely sure there is a fair shot at them sticking around a while (well as sure as you can be). And I absolutely agree, it's best for the kids.
However what that means in reality is if you are a single mum, with a useless ex and support system babysitting either non existent or used for work or limited to a fairly reasonable night out a month, you may as wrk forget seeing anyone.
AIBU to think if you do try to see someone other than sneaking the odd coffee in during maybe working hours you will spend your entire time saying you aren't free/can't get out/giving big belly laughs at the idea of a night away
