Saying "I love you" for the first time.

So, I feel absolutely ridiculous about this, but I don't know where else to go for advice. So I've been with my boyfriend now for 5.5 months he's 24 going on 25 and I'm 23 going on 24, (my son is 11 months and he's not the father, nor is the father in the picture) and there's no doubt about it that I have now found myself falling in love with him. Everything about him makes me love him. He's caring, sweet, thoughtful, great with my son, understands what I'm going through or at least tries to. He has intentions to buy a house within the next month, and he asked my son and I to move in once I am back working (soon). 2 months ago it was jokingly brought up talking about "love" and I said I wasn't going to say it until I know for sure and can mean it. Well. Now I do. He hasn't said anything to me, and he's not big on talking about feelings anyway. I need a way to tell him I love him. Without being over the top corny. I'm shy with just bluntly saying it or when to. All my past relationships were blurted out to me, and I just said it back. This is the first time I know I've truly fallen in love with someone... So it not only means a lot to me, but this is the first legit serious relationship I've had in 4-5 years.
