Two time single parent.. I feel so stupid.

I was previously married and have a 4 and 6 year old, their father is not involved (or very minimal and does not have regular visits or the ability to care for them). I had a boyfriend of 2 years who I unexpectedly fell pregnant to. We were happy to keep it, while not planned we took it as a natural course in our relationship.

We now have broken up and I just feel so stupid that I’m now again a single mother to 2 different men. I have no idea how we will share custody as he lives a couple of hours away, he also has a son who is 10 and lives close to him and he has him each weekend. I don’t plan to keep the baby from him since he is the Dad but it just feels like a mess.

I have 2 and almost 3 young children without a consistent Dad. And being a single mum is a struggle which I’m used to. It just feels unfair to my kids :(

Any advice welcome.
