Advice Needed please?

The father of my youngest son told me he loved me last night. He was drunk. He is usually a very closed person with thoughts and feelings so it caught me off guard. He also told me I've grown on him as well and he is super affectionate. Just a quick history recap, we started off as friends with benefits and I ended up getting pregnant. We had our differences and disputes but we have been amazingly coparenting so in a sense everything started off a bit backwards. Should I take what he said with a grain of salt or should I believe him? I'm so confused. I'm happy but at the same time scared. I felt with a domestic violence relationship 7 years ago but I'm working on my triggers and bettering myself for me and my future.
