Giving up

Well Aunt Flow came today much to our dismay, over a year or trying, countless tests, Doctor visits and one miscarriage we have decided to quit trying. It’s just putting to much stress and so many emotions. I just feel bad because i have two children with my exhusband but my current significant other has no children of his own so really feel like I am letting him down. DX one blocked tube and just can’t seem to get the other to jump on board. I guess somethings are just not meant to be in the cards which we will come to terms with but how does one handle the thought of not having anymore children or not having one at all?
