Where the fire?

my boyfriend and i have been together for more than 3 years. when we meet we use to have sex anywhere and everywhere. we didnt care but know that we have a had a son it like he only want to do the basic. we use to go out on dates. now the only time we go outside is because his friends want to hang out even then i dont go all the time. we haven't been on a date in more than a year. i have set up about 5 dates in the last 2 months and somehow we either dont go or he being his firends with us. i dont understand what going on! he rather be with his firends or be by his self than with me. WHAT IS GOING ON?
