Engaged!!

my boyfriend (well not fiance) just asked me to marry him and of course I said yes, I want to spend the rest of my life with him. little back story, we met right as I was leaving my abusive husband. none of my family knows he was abusive just that he was an asshole. anyway we weren't married long but we're together for 3 years. I met my now fiance and we got pregnant early, but both fell really hard for eachothers and it's been constant love since. I've never felt this way before. we've been together almost a year and a half we have a 5 month old baby together. I guess I'm just really nervous about how people will react. I love this man more than I've loved anyone and want our family to be whole. thoughts?
