Marriage breakdown when to tell teens

[Tunnelight]

My marriage has broken down and we have separated. Separate bedrooms same house, civil but snipey atmosphere.
We have 2 DS, one at university who understands the situation and younger who is 1st year a levels and is either ignoring or is hopeful we will get back together.
Problem is when to tell them we are selling the house and splitting.
Do we try to stick it out until younger A levels are done and he has left for Uni?
Or get it out in the open and tell them we plan to sell up after a levels.
I know that there is a third option to split now, but I would have to stay local for DS school and I would prefer to move away?
Any advice, experience, opinions, please.
Thank you

If you can, I would wait until after A levels.

However if the atmosphere is bad, and you suspect they know anyway then tell them now. The anxiety around what is going to happen will be impacting on them.

Just be honest. Explain what's going to happen and time scale.

Also if planning on living in same house make sure you have rules. Like both cook and clean for yourselves. Have repeatedly food cupboards and do own shopping. Both sort out own phone, car etc bills. No 'guests' in house. If your cooking and providing wash stuff for DC he should contribute costs.

I mean, I'd tell them now. If you're living in separate bedrooms then your at home teen is 100% aware of what's going on, and a backdrop of uncertainty and unhappy parents for the next 18 months is going to be more detrimental to them (imo) than being told what's going on now.

Tell them now. They're going to know something's up and be worrying and stressing, best they know the facts.

Thank you. I know honesty is the best policy. I'll gather my courage.
