Hi MOJITO, sorry you're going through this, it must be awful.
Sometimes it helps to see things from different perspectives. We only ever see things from our own perspective and well, the world is more complex than just us.
We're probably about the same age guessing from the info you divulged here. I have 2 young DC and two years ago my ex walked out and my whole world caved in. I no longer had choices, I was forced to go it alone and, I might add, with the pain and emotional heartache of having been rejected by by OH.
It's rough out there on your own as a single parent. I know lots of people would say new chapter, turn the page, blah blah blah. But at our age and with our baggage it is not easy finding a new partner that fits the bill.
My point here is I do believe you are doing the right thing. You DO need space, I'm sure. You need space to realise that your man is human, he will fuç€ up like 98% of other men on this planet. He says he loves you, you love him..... imagine life without him. Imagine being alone and not being able to find anyone whom you feel as well with. Imagine having to do everything alone, practically, physically, financially, emotionally.
I will never stop insisting that it is so hard going it alone, unless you're that way inclined and unless of course your OH is an abusive good for nothing.
It doesn't sound like that. Counseling can be fab, as can rediscovering each other, getting your sex life back on track, finding the time to be individuals and then quality time together and as a family.
I wish you all the luck in the world and really hope you find the courage and forgiveness to make your couple work. Hugs Lemon.
