It's tough after any breakup, especially a long term relationship- not just a divorce. Especially if no family around or you're estranged.
I find myself spending this Thanksgiving alone. Well not entirely. Saw my 93 year old dad at his independent living home for a couple of hours, got served a turkey meal for lunch, I was the only visitor there were about 20 senior citizens there. I do have a girlfriend, we're 5 months in, but it's casual, not sure where its going, she's over an hour away, we didn't make plans to get together today, and yes that's a sign of where we are at although she's coming to me for the weekend.
My prior relationship was 10 years and we'd go to her sister's house, there'd be at least a dozen family members, spouses, kids.. lots of drinking, lots of loud conversations, lots of bad food. I found myself not wanting to go the last few years and counting down the minutes until it was time to leave. Now that it's over, and I'm sitting here on my couch alone in my house, I miss it.
