I have been seeing my boyfriend for 6 months. He has 19 and 14 year old sons. I have 18, 15, sons and 12 year old daughter. We were high school mates back 25 years ago. Ok so.. Every since his ex wife left and they divorced over a year ago, the 14 year old son sleeps every night with his dad. He has his own room and bed, but only will sleep in bed with his dad and dad allows it.. Even at times encourages it. I think this is rather strange. I have only allowed my children when they were very young to sleep with me and only when they were sick. How long is long enough and how should I approach this or should I.
Please help me I need advice

I agree, this is a strange situation. Do you think you would have moved in with him six months ago, had you known of the 14 year old sharing a bed with his father?

Where do you sleep!

Yes, I would most definitely bring this up. This teenage boy needs his own room, and his own bed, and your boyfriend is not doing him any favours, or encouraging his indepence (age appropriate), by allowing this to continue.

I would think that the other four children are old enough to think this is a situation that isn't right either.

Without knowing why this is going on, and if he is, or is not, willing to take steps to address the issue, you remaining silent will not change anything.

There may be more clues to how he responds to your concern, when you talk to him. Without knowing anything about the 14 year old (insecurity, fears, etc.) it is hard to advise you further.

But yes, my opinion is, you need to address this.
