hello! random pop in to thread because it is I think a safer place to put an update than FB, which is where I usually chat to quiche people 
It's odd to explain, but I'll try.
So after S was born my marriage to DH went up the shitter, for various tired old reasons. He is a difficult person to be in a relationship with in a couple of key ways (forgetful and unreliable, for example), and these were infinitely more difficult to cope with in the context of financial stress and the early days of mothering. But sometimes I think I just never loved him enough to get through the baby stuff.
We moved to California from London as was always planned just over a year ago, and it was hell on earth. tearful MN threads under different names. I was rock bottom. No friends, no life, no money, no way to get around, awful MIL to deal with. After a couple of months here, I came back to the UK for a brief trip and as it happened, I had issues with my visa and wasn't permitted to return to the US (a direct consequence of DH's unreliability). So S and I were homeless with a bag I'd packed for two weeks, the week after her first birthday.
Skipping over some of the more hellish details, I decided to turn circumstance into a separation from DH. After a few months of being gypsies, I got me and S settled in a flat and things improved hugely.
And then - this is the bit that's hard to explain, even to myself - I decided to come back to the US. (My visa issues were resolved after 6 months, so it became possible). A huge part of it was I couldn't bear the responsibility of parenting entirely alone (and it would have been entirely), nor taking S away from DH, who is a crap partner but a lovely person (if you're not married to him!) and wonderful father. Another big part of it was a shower of shite in my family that has left me estranged after a lifetime of being close. P
So here we are. DH and I are still married. I am here as his wife so won't go into it too much, but the future of my marriage is far from certain - I just want to build a life for myself - work, and money! - and then decide. I look after S full time still, and DH goes out to work, and we all rub along. Things are better than they were last year, because I can drive, and I have a work visa, so am looking for a job.
Who knows what the future holds.
