My partner and I have decided to separate. It's still very recent (we talked about it properly this week) but not unexpected and so far, amicable. I hope that we have the basis for being pretty good co-parents and friends in time.
It's hard to know what happens next though. Money is an issue and, as my parents live close by, STBXP is suggesting that I should move in with them and have DS with me some nights, while he stays in our flat and has DS the rest of the time. This would then mean he wouldn't have to rent a place himself separately and would make it easier for us to repay some debt we've got ourselves into (not huge debt but enough to be quite stressful for him). His other argument is that he is more domestic than me and does more of the bedtimes anyway, which is true but at the same time, I have a very close relationship with my son and out of the two of us he relies on me a lot more emotionally. He is only three and I'm worried that if I go to my parents and my partner stays put then a) it would be more emotionally upsetting from DS's pov and b) essentially my partner will become the resident parent and I could end up with only having visitation rights? Does the fact that DP is so hands on mean he could be seen as the main carer?
I can't force my partner to move out (flat is in both our names) and I do see where he's coming from but I would be much happier with him lodging somewhere nearby, coming over to spend time with DS several nights a week (he would also have him every Wednesday during the day and every other weekend, he works alternate weekends so that makes sense), and if he wishes I could stay a couple of nights with my parents so he can stay over with DS at the flat.
Does that sound like a sensible arrangement, and am I being paranoid about the potential to lose custody here?
