Someone said you can be happy OR you can be right - you can't always be both!
Gransnet, hmm, given my parents (late 60's) and my grandparents (if alive would be early 90's now) never had any problems with me or my siblings or cousins staying at theirs with our partners in the same bedroom, in the same bed I'd be very surprised if you didn't get a similar response there! Plus they're all Catholic!
I'm not much younger than you, if my first pregnancy had been successful they'd now be 25, I have a 15 year old daughter.
My parents let my boyfriend stay over from 17 on, same rules applied to my sibs as they got older, no one night stands or flings but steady relationship partners were welcome once they were age of consent.
Over time for me that applied to 3 boyfriends (one went on to be husband) and one girlfriend (now that would probably send op into a fit!), siblings Have each had 2 serious partners, only one wedding in there.
The siblings had their children out of wedlock too
.
My ex's parents (who are now late 70's) APOLOGISED for the fact he only had a single bed at theirs when we stayed there! (Tiny room a double wouldn't have fit).
I've met 2 people like the op, both have very limited interest from their children as they've got older and rarely get to see their grandchildren.
As far as the financial/living arrangements:
No he shouldn't be having his mother paying his mobile phone bill.
Op shouldn't be expecting rent or odd jobs from an adult who is to all intents and purposes no longer living there (can't imagine why
).
As he has a job that requires him living away part time, I suspect given the current economy and that he hasn't been on a full time wage for long and he and the girlfriend still quite young, that they're staying at her parents at weekends to save for their own place probably which is totally normal and common now.
