Depressed Mom

My father then 46 (2023) suddenly divorced my mother 38 saying she was too boring to live with and didn't suit his lifestyle. But she still got half of everything on top of the house and alimony. My father didn't care about me, as I then 20 wasn't a go getter like he was his words. I was happy with that; I stayed with my mom and self-supporting myself. My mom was very depressed by the divorce and seemed to retreat into herself. A year the divorce was final, my father died in a car crash with his then girlfriend, a single vehicle accident and drug's residue was found in their blood. My father hadn't updated his will since the divorce and I got everything. Both my mother and father's wills left everything to me, he must have been too busy enjoying himself to update it. But my mom was still depressed, I decided a change of place would benefit us both, carefully choosing a place she and my late father never went too. Didn't want old memories surfacing, rented a condo on the coast in a quiet area away from the crowds. The condo had its own private beach not very large but big enough for us. It took several days for my mom to let go and start enjoying our holiday. One thing led to another and we became lovers, mostly because we over drank too much wine. I was really quite happy becoming my mother's lover she was really ashamed for a time at first. But with me still trying everything to bed her again, her mood changed for the better and she started to sleep with me again before we returned home. Only unforeseen part was her getting pregnant I was shocked at first but quickly got over it. With me happy with her being pregnant to me and she also became happier with being pregnant. Our daughter is due in 3 months or so, very healthy according to all tests done. My mother still wants me to marry but sleeps with me every night and hope to be a proper grandmother she says. Not the mother grandmother combo she is going to be soon. I'm quite happy with our current lifestyle, but I'm still looking for a suitable girlfriend to make my mother happy. She isn't so depressed anymore that a great improvement, I think.
