Shouldn’t love be easy?

My man and I have been together for almost 4 years. We long ago crossed the boyfriend/girlfriend/dating stage and are long term partners. Lately I've been feeling the magic is gone...it feels less connected, less attracted, less exciting. Do you think this is just part if normal settling in; a shifting in dynamic that is inevitable? Or a sign that its not working out?

Do I love him enough?

My boyfriend and I have been together for three years. So far things have been great; we've had normal couple issues but nothing too crazy. Over the past couple of days, though, he has been saying 'I love you', 'I'm so lucky to have you' and 'you are beautiful' about four hundred percent more than he usually does and I'm feeling really guilty that I don't seem to feel it as much as he does.

Can I say I love you first?

OK so what's the deal with the first "I love you"?
Can I as the woman say I love you first, or is that one thing the man for sure has to say before the woman? I've read that, in general, men take longer to fall in love than a woman will, and we don't want to say I love you too soon and scare them away. Is this BS, or good advice? My heart is screaming to say it, but I'm worried about going too fast for my boyfriend.
