<human>: Condense the text into a few key points

We have been together for 8 months now and for the last 2 months we have been together almost everyday (like 5 out of 7 days a week). It's starting to feel we cannot be apart for more than a day (yes becoming like family) but at the same time it's boring and experiences are not very novel for a couple. We are both in our finals so extremely busy with work and exams so most of the time we would be either in our room, in library, cooking or at a local restaurant. 

I love him like an older brother and care about him a lot but I'm not in love with him. I know the feelings when I'm in love with someone, and it's invigorating, exciting and nervous but with him it's more like friendship, or family. 

I don't know what to do because I care about him but I cannot look at his eyes and say "I love you" back. He really cares about me too, but I don't think it's enough to say he's really in love with me.

We had dinner with a friend today (C) and she's absolutely the hottest girl I know at college. I don't know if I'm ultra sensitive but she was flirting with him with her body language - whenever she's with me she never touches her hair or caresses her collarbone. And he said to me before he thinks she's attractive but he is not interested in her, but today, for someone who is chronically late like him, insisted me to come to dinner on time for C which made me wonder if he's anxious to meet and dine with C for the first time. 

So does he have a crush on C? And if he likes someone else, I don't want to be with someone whose I don't have a romantic spark with. I don't want to be with him just because I really care about him as a friend/older brother.
<bot>: Should I continue to be in a relationship with someone I don't have a romantic spark with and I think he's having a crush on someone else.
