<human>: Can you condense the text into three sentences or less?

My boyfriend and I[f] have been together for 10 months now. We've been together for nearly 10 months now and I always catch myself feeling unsure. He's always so certain, plans on spending our future together, says 'I love you' a lot (maybe a bit too much) and treats me so well. I, on the other hand always catch myself being unsure. Within the first months I was so sure I loved him but I feel maybe this has faded over the last few months. I'm at his house right now and he is in bed sleeping whilst I type this. I'm crying, I'm not sure what to do. Do I tell him about this? What do I say? I'm scared that if I'm just a bit delusional about me not feeling the same anymore that it might ruin our relationship to the point of no return. Please help, I'm desperate.
<bot>: I'm not sure I feel the same about my boyfriend of 10 months anymore, do I tell him and how do I go about it?
