Why do nice guys have to finish last?

About all i can say is just be yourself and keep trying, the right person is out there just waiting to be found, someone who will appreciate all of your qualities and not only "get" you for who you are, but dig it too.

I am out of ideas so posting this here in hopes you all can help me. I am a nice guy, its just who i am. Anyways this is my trend right now . I go through GC , and talk to a match, things go pretty well normally. And often talk on the phone a couple of days pretty heavy and frequent then go out on the first date, things seem to go well. I am a gentleman, for me its who i am not a means to impress. My date and i talk usually for a long time after dinner til one of us has to go. I walk my date to her car and say good night. normally the feed back from my date is " your just such a really sweet nice guy" followed by a hug. (also about 50% mention they think i'm a "cutie" ) That phrase is starting to become like the kiss O' death to me because , they say its alright to keep calling them but its normally the last date they end up going with me. At this point i think everything is going good normally if you asked me how the date went most of the time I'd say " i think it went pretty well" ( but then as my profile would tell you i sorta lack in the area of perception.) From the next day on I don't start to hear from them as much after as i did before , i try to stay in contact, but it seems they are not as interested to talk to me for the same length of time they did before the first date. and sorta feel blown off. Like example what was once normally say 3 to 4 hour long chats gets reduced to 15 to 20 mins. Til eventually they tell me again how sweet and nice and wonderful i am to them, but they feel no chemistry andthey feel we should see other people , but yet still want me to stay as there friend. I just don't know what I'm doing wrong I'm polite, honest, sweet, respectful courteous, generous, tolerant, forgiving, , thoughtful, sometimes even pampering. I'm from the old school of thought where the guy Always pays for the date. Now granted while i am 35 years old i don't have a ton of dating experience, due to I was in a 12 year relationship in my life with my ex wife who i was married to for 10 of the 12 years. but i don't know what i could do different. Really including my ex wife have only been in 3 relationships my entire life, one of which was after my divorce and , probably only went on dates with only about 5 or 6 people since my divorce, and 2 since my last relationship. I'm very open and pretty hard to offend , but do any of you have some advice for me, like how i can improve, or what my problem area is? what I'm looking for is a relationship. I'm also a one woman kinda guy , i don't multitask well and learned early in life its best to keep things simple so i tend to focus on a single person at a time til i know if anything is gonna happen between us and if not i move on to the next 1 person. I have ADHD and it seems this is the only way i can do this, is 1 person at a time. Anyways thanks for your help , and take care , I'll keep my eyes peeled here to see if anyone responds.
