I can't give any advice in how you should handle your situation as each new relationship is unique. My daughter was 19 when her dad passed. They were close. She moved out about a year after he passed. So basically I was alone alot. Eventually she told me she didn't want me to be alone. My husband and I were married 22 years; together for 27 years. More than half my life when he passed. Like at that time that was what I wanted. Have someone new. I eventually decided after 6 years of this journey of Hell on Earth I needed to do something to get me out of the rut I was in.
I tried online dating. OMG, that was frightening. Scammers, weirdos, creeps. Had absolutely NO idea scammers were out there. Anyway, eventually I chatted with this one guy. After a month of online chatting he asked me when would we meet. To make a long story our 3 hour coffee date has turned out to be a full fledge relationship. He recently moved in with me. This past Mother's Day my daughter gave me a Mother's Day card that brought me to tears. In it she told me she was happy that I found someone to make me happy. Luckily, she and the new guy hit it off right from the start. Always greets him with a hug and her fantastic smile. Eventually the new guy and I plan on selling our places and ride off into the sunset in our RV and see what else the good Lord can show us. It also helps with the relationship that he is widowed as he gets it. So no problem talking about our spouses without any competition.
As each of us handle our journey of widowhood, someone is not always going to be happy. But for me it took alot of patience. We all need to do what we need for US. For me I come first. If I'm not taking care of myself I'm no good for anyone else. This includes my daughter, other family members, friends and of course, the new guy. By the way in a few days it will be 3 years and one month since I met this fantastic guy who brings a smile to my face everyday. Actually we don't count years. We count months so each month on the 20th we say "Happy Anniversary" to each other with a smile and a kiss.
