The grass is always greener on the other side of the fence.
I've been married and have had a few other live in relationships over the years, and have had plenty of girlfriends in between. From the age of 20 to 49, I was single a total of nine months, as I immediately got into a new relationship when one didn't work out. (By no means am I trying to sound boastful, as I find my jumping from one relationship to the next unflattering ((hints of codependency? )) and I am merely trying to offer a different perspective).
Prior to the age of twenty, I struggled to get into a strong and committed relationship and felt like many of you on this board. Before the age of 20, I was incredibly depressed every New Years Eve, in particular, being single on that day seemed tortureous to me.
I'm late middle aged now, have been single for several years, and have zero desire to be in another relationship ever again; and, I choose to no longer date, and on that front, I couldn't be happier.
Everyone should have the experience of being in a loving relationship at least once, but I can assure you it's not all it's cracked up to be, especially after the honeymoon phase is over. Just look at how many members on this site are having significant problems with their respective spouses or significant others. Look at the divorce rates where you live. I'm in California and the rates are sky high!
I fully understand what it's like to feel a void by being single and inexperienced with love, but don't be fooled by what you perceive it means to be in a relationship. Most of what you see in the movies, on social media, and out in public is an illusion.
