<human>: Give me the gist of the text in a nutshell

A bit of backstory: In april 2013 I came out of a 4 year relationship, this guy was my life and I invested way too much in him, I didn't know how to cope without him.

Fast forward to summer, I slept around a bit, and finally met this great guy, expected nothing from it as he's way out of my league, but we ended up together. We've now been together 5 months and I've fallen in love with him, to my displeasure. I didn't want things to get too serious because I still felt vulnerable from my break up and I'm absolutely terrified of counting on someone to just have my heart broken again.

My boyfriend, let's call him O, is really not good at communicating. He occasionally lets slip that he has feelings for me and feels rather embarrassed. I'm a poor communicator because I've built up these walls. From conversations we've had in the past, I know he's skeptical about love and "doesn't do feelings". Basically, I'm terrified that if I tell him I love him he'll freak out and decide it's too much to handle and consequently leave me.

Take from this what you will, I said to him the other day, post-coitus, "I'm really falling for you" (i said this to gauge his reaction) and the response was "oh, aren't you sweet". I'm really none the wiser as to how he feels about me.

So, reddit, my question is, should I tell him I love him, or is it too soon?
<bot>: boyfriend "doesn't do feelings", I've been hurt in the past, I've fallen for him, do I tell him how I feel?
