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

My boyfriend and I have been dating 11 months. This September 21st it will be a year. Recently, I feel like he's been losing interest in me. I'm not sure why.

I know he doesn't talk to other girls or has interest. And he always wants to be with me. But lately he's been very unresponsive towards sexual advances. Maybe it's because we just got back to college? Finding alone time is quiet hard considering my roommate never leaves the room, he lives with five other guys, and he isn't in to the whole public places deal...

Basically he's stopped sending good morning and good night texts which were always a daily thing. He also is never the first person to say I love you anymore... I'm concerned he may be loosing interest or getting bored and may just not realize it (he's 21 and I'm his first girlfriend...ever...first everything really...) 

I just don't want to be stuck in something that is slowly disintegrating in meaning to him. Am I being over dramatic/crazy? Have any of you been in this situation?

Also important to note I have a bad track record with men. I've never been dumped. Always the dumper. And for some reason it always happens around that one year mark. I never noticed this until my best friend pointed out I've had this pattern with the six other men I've dated. 

Because of the above I don't know if its him or if I'm just falling back into patterns and maybe even subconsciously looking for a reason to end things...I love him so much and I haven't felt this way about anyone...

Thoughts? Advice? Opinions?
Thanks.
<bot>: I can't tell if his slow decline in the sweet things he used to do to showed me he cared is a sign of interest lost...
