I'm so sorry you're going through this
My exdp left when DS was 2 and a half because 'being a full time dad was too much hard work' - this was after I'd forgiven him for multiple affairs. I remember feeling like the bottom had dropped out of my world and feeling completely heartbroken and then having to deal with the panic of practical things - how to switch bills over, could I afford it, the minefield of benefits - and also feeling terrified of how judged I would be. I remember saying to my mum at the time that it physically hurt to breathe. That lasted a little while.
But I posted to offer a little glimmer of hope even though it'll feel like such a long way off yet:
- exdp left about 5 years ago. I am now a far more determined, independent and happy person than I ever was with him.
- in a way I am much more confident; in that I know that whatever life throws at me and DS we will get through it and things will be fine.
- DS and me are very close and have an easy relationship for the most part. His dad struggles much more with him
- I have built an amazing network of friends and family over the last few years. Exdp made sure I was quite isolated whereas now there is always someone I can call, whatever time of day it is, if something happens. I'd never have that network if he'd stayed
- in retrospect, I don't think I'd have ever had the guts to leave if he hadn't and I would be miserable, constantly telling myself that it was hard because that's how relationships are.
What helped me in the early days is also what scared me the most: practical things. I made a list of all the bills, prioritised them and called 2 a day until they were sorted. You can't really plan financially until you know what benefits you'll get and what maintenance you'll get so try to make a loose plan and then let go of worrying about that as much as you possibly can until you have that information. Set up a contact schedule with your ex for when the girls will stay with him. Do this as soon as possible. It will be hard for a while to not have them with you (I didn't sleep for about the first month's worth of contact) but you need that time to do whatever you need to after holding it together in front of the girls (the first couple of times DS left I would just curl up in bed and cry, it gave me the strength to paste a smile on when he was back).
Also, the most important thing that helped me was the list I made which consisted of everything exdp didn't let me do, from little things like have a glass of wine in the evenings, to having friends round, to the big things like my degree! I used to do something every time I felt at my lowest and it helped.
Lastly, and this is really hard, try not to focus on why he left. You have to learn to not see him the way you have done for all the time you've been together. IME men are much better at doing this. I spent a long time asking exdp why it didn't upset him that we didn't have smalltalk anymore, that I still wanted to tell him about my day each evening etc (I know, I look back and cringe). Whereas, for him, the minute he made the decision to leave, I wasn't his partner anymore. I wasn't his friend or someone he loved. I became
just the mother of his child. So he was civil but detached. I wasted so much time trying to convince him that I was enough and driving myself up the wall thinking of the woman he ended up with very shortly afterwards. That's the only thing about that period of time that I regret but I accept it's pretty hard to separate yourself!
Also, another thing (sorry, I know this is ridiculously long) please please don't worry about people judging you for being a single mum. I've only come across one person that made a catty remark about me being a single mum
and he was a dick, everyone else has been supportive and said they really respect me for managing on my own. I think there's such a cliche in our heads of how society views single mums but, in reality, that attitude doesn't really exist as much anymore.
Sending big unmumsnetty hugs. I remember my DF saying to me when he found out "I won't ask you how you are because I know right now you'll be feeling like shit, all I will say is that you
know you're going to be alright, it's just the getting there part that's crappy" and it was so true. You're going to be fine. All the firsts are the hardest - e.g. First birthday, first Christmas etc and then it gets easier. You just have to ride it out.
