There are great role models all around you but you may have to look for them. They don't wear signs and they don't advertise so you really have to get out and search. They are busy going about their lives doing everyday what needs to be done. Again you may have to go looking but they are out there.
There are some really great guys here on the site you could get to know too. I have latched on to a couple who have been very valuable in giving me insights and advice. I have found one or two here where I am geographically but I am selfconcious about approaching them to begin a friendship because I feel so damaged that I wonder if they will want to hang around with me. You may feel that way too.
Honestly you dad is watching your life and seeing you make progress. Who knows you may end up a role model for him. It is never too late.
These wounds are really tough to deal with but they can be healed if addressed and not left to fester. You are doing good so far reaching out, asking questions and putting into practice the good advice you get. That is really all anyone can do and it works as you have seen. I am glad your here and when you look back you will be too.
