Same here. My late husband and I enjoyed each others' company, and we worked together on projects; we were rarely separated (except when he worked). We went everywhere (mostly) together. It was a lot of fun, and we could talk about it afterward. We traveled together and went to the theater, parties, and lectures. There was always something stimulating to share. I didn't have my own friends then because we had many friends "of the family" and he and my son were my world. Later, when I began going to orchestra rehearsals and taking art classes, he didn't come along, and I think he felt left out. He had retired recently. After he passed, which was a heartbreaking time in my life, I eventually started going out with female friends, but it wasn't the same. There's something about an intimate relationship that can never be substituted by others, in my humble opinion. Everyone is different, though.
