Good luck. I went through the same thing when I found myself as a single dad. I tried a couple of times, but after seeing my son affected by one of the breakups, I didn't have the heart to try again. Perhaps I should have, because much like you describe, I find myself feeling the loneliness and longing for something I know is missing in my life. Now, at 52, I find myself believing that I'll die alone because of the years and my disconnect with what women want from guys. My last few attempts were shockingly bad because what women want today isn't what they wanted in the 90s to early 00s.
