Hi. I could have posted your message almost word for word a few years back.
I met a wonderful man through online dating. I had the same insecurities and over analysed every aspect in the end. The result? He called it a day! And I truly believe I lost a very good man.
He was very patient with me when I first confronted it. In fact, he was patient several times when I confronted the same issue. In the end, he said he couldn't do anymore to put my mind at ease and said that I was beginning to make him conscience of how he replies to texts, how I will react if he can't see me etc. He said I was trying to force things rather than let them develop naturally.
I was heartbroken and tbh, it was hard to go back from the beginning and start again. I'd put him on edge.
I lost a great guy, and ended up meeting a guy that promised me the world from the beginning, loads of texts, loads of his time (all what I craved with previous man ) only to bring me crashing down to earth a couple of years down the line... he was a cheat, lost interest, got quite spiteful etc) I'm strangly grieving this relationship currently. But I know in my heart, if I was patient and trusting with the first guy, I'd probably still be in a very happy and equal relationship .
Please take my advice and chill out a bit. Sometimes it's good to let it develop slowly.
