I split from my son’s mum around 7 years ago. It was my choice to move out. Ever since then I have tried to be as nice with her as possible. I have basically become a bit of a mug. I was in a relationship for 2 years which ended in October of last year. I introduced my son to my new partner but slowly & after a year. I made sure my son felt comfortable & I always put him first. Sometimes my girlfriend would stay over with her daughter & I always notified my sons mum & we all slept separately. My sons mum made a point of telling me that I better not start neglecting our son when I got a new girlfriend & my girlfriend better be suitable & safe around my son. I just bit my tongue.

What is really concerning me no is that my son’s mum has finally found herself a new boyfriend & is doing everything that she warned me against doing. She has basically not taken into account our 12-year-old sons’ feelings. This guy is round there staying nearly every night. My ex has tried to get my son to hug him. The guy is an ex heroin addict & has served time inside for perverting the cause of justice. He doesn’t work, looks very untidy & lived with his mum at the age of 31. My ex is almost 50. This guy allegedly keeps telling my son that he loves him which I find totally weird. I was having concerns before this about my son’s welfare due to his mum’s behaviour anyway & this has just put me over the top. I have my son stay 4 nights & I am already currently paying too much maintenance to her. I have no idea what to do & I am apprehensive of doing anything official. My Son’s mum is a compulsive liar & good at it & she would be able to lie herself out of any allegations.

Is there anywhere I can go to discuss these things without making an official complaint or taking legal action?
