Single dad for 11 years now im in love with a woman ?

Hello, i am dutch from the netherlands,i am new to this internet site and also please excuse my english.i was married 15 years ago but split up as my Ex wife did not love me as she fell for someone else .i have two kids both boys who are 12 and 13 me and my ex wife split up when my youngest boy was a baby she is not in the picture and so i took care of the boys myself while she moved on with her life . i then went out to look for job and became an accountant as i had a degree in it this was 10 years ago i am now there happy working ten years! A woman who is now one of my best friend joined my working place 2 years ago and we are so close .she is not dutch she is from over seas in ireland and spent time in england also.but is irish.She told me all of herself all her past and i know all about her and visa versa .we started as friends to best friends but now i love her and at first i didnt want to believe that i did but i do i want to be with her .me and my boys like her i spoke of her to them and they like her as we meet up some weekends infact she also babysits when i need the help.My boys are ok if i did start a relationship with a woman i told them that i would always be with them and take special care no matter what .i just want a woman in my life to make me more happy i love my sons and would never leave them out.i have deep feelings for this woman for over 10 months now and i wish she could see i liked her i have dropped many hints.she did kiss me once but we were drunk at the time so i dont think it meant anything.How do i know she might like to join me and my family i think it would be beautiful to have her as a part of me and my boys because she is caring beautiful and funny and i think she is just so perfect in everyway!I have never touched or had a relationship with a woman since my Ex wife and this new woman is the first that i have ever grown feelings for. How do i tell her i love her and want her?
