Normal?

Kinda a long story so please bear with me....

I was married for 12 years and thru my now ex husband I met this guy, they were best friends. Then we moved 3000 miles away and we both kept all kept in contact thru social media, and I saw him a couple times briefly when I came back for visits and such. Then I was in a near fatal wreck and my then husband decided "He did not want to worry about anyone anymore" and went and found a girlfriend, I found out about her while I was fighting to live still. His best friend did not agree with this and tried talking sense into my ex to no avail, he was met with silence. He became my rock thru all of this. Always checking on me, making sure I was ok physically and mentally. He knew I was a wreck, I moved back home 6 months later and this man was there for me at every level. He did everything he could to help me heal both physically and emotionally. He is my best friend. He knows me better then I know myself, and he constantly looks out for me and is very protective of me. We have an incredible bond and connection to one another. Needless to say I feel in love, completely. I know he is healing emotionally from a bad relationship, one the destroyed his self esteem and self worth. He has told me he has had feelings for me for 7 years, but has not ever made them known because I was married, and to his best friend no less. So we have been extremely close for the past year since I have been back.

Last week we had a conversation about us, it is the first time he has been so open with me. I had about given up on ever having a relationship with him and I went on a date. I told him about it and he asked me if I thought it was something that might get serious. I told him it was hard to say after one date. Then I told him it almost felt like I was cheating on him, even tho we are not together. That is when he opened up to me. He told me I am his best friend and he can see spending the rest of his life with me. He said his ex messed with his head so badly that he is scared now, scared of disappointing me, fear of failure, fair of not being good enough. He said "I only want the best for you, no matter what that looks like. This guy might be your soulmate, who am I to stand in the way of that? I love you, always will. You are an amazing woman, theres no-one else that makes me feel like you do". Needless to say I decided not to go out with the other guy again so now I am back to waiting to this guy to "Get right with himself" (He said he needs to get right with himself or everything else will self destruct). I get that.

I lost a very good friend of mine very recently and it hit me very hard. He was always checking on me and stopping over to make sure I was ok because he knew how hard it hit me. He could tell thru texts when I was not quite right and would come over to make sure I was ok. He said he was very worried about, and I asked why. He said because you are clearly grieving harder than you originally let on" I asked if it was that obvious, he said it has been that obvious since it happened. Again, he was there when I most needed someone. I did not ask him to be, he just was. I told him I tried to hide how bad the grief was and he said "You dont need to hide it from me, I KNOW you. I can feel the pain you are in. You don't need to tell me, I feel it". He had come over the day it happened and just held me and let me cry, yell, scream, whatever I needed to do. He later told me that day connected him to me forever. That I trusted him with my vulnerability that day. While he was holding me he kind of whispered "You aren't going anywhere, you're mine." I asked him later if that was a comment made in an emotional moment or if it was his way of telling me something more? He said "The comment came from emotion I was feeling at the time, but I know we would be great together. I am starting to figure my shit out and I am sure this will be official sooner than later."

Is it normal for a Saggitaruis man to have feelings for someone for so many years, to really connect with that person and have an amazing connection and still hesitate this much?
