I need some advice please.Me and dh are good friends with the couple next door.We see them every day,go out together,talk for ages,and dd's are best friends.Then just after mother's day on the wednesday,my friend told me her dh had decided he was leaving her.Big shock she had no idea anything was wrong.He said he had felt like that since november.Anyway my problem is my ds who is 19yr spends alot of time round there.I have asked both of them if he was in the way ect and both said no.She is glad he was there,my ds was a shoulder to cry on for her.He would knock every night to check everything was alright.Now he spends most of his time there,saying he sleeps on the sofa.We have joked that he is her toy boy she is 31,but i'm starting to wonder if there is anything going on.I have said afew times things like age doesn't matter ect,but they say they are just friends.Do you think i should ask my ds out right or leave them to it.Her dd's don't know he sleeps there.
