fool or not fool?

I've been recieving these messages for the last 2 days, and I've noticed basically that I could care too much ,among it, I'll quote my dearest once again: " u are such fool, to worry like u do" , then I wonder, "am I? , or am I right on the things I'm worrying about and the signs are just evident?"So confusion starts over again. The point is, I don't know if I should talk about it with anyone at all, because it's a delicate issue , plus I'm not quite sure about anything in that matter. Sometimes I do feel it's real, and that I feel it.....and then it's like: I'm not anymore. Now I've been noticed some weird attitudes , like taking the cellphone away when leaving the place for like 2 minutes or less, working late too much lately, and what makes me doubt even more, when his mother was here, he only worked late once, it's suspicious to say the least, plus the other he was "too tired", does that even happens with guys??? I think something's off..... and for other reasons I think I shouldn't worry, but I don't know..... there's so much that doesn't fits in how a relationship it's supposed to be, then I got an advice yesterday: "it'll never be how it's supossed to be" , so I think that maybe that's it.... then I'm scared of letting go as usual....I'm always afraid of that, that's why I need some more ATYCLB in my life, to help me go through with it....it's so freaken hard. Then I go like: life is short, I should just enjoy this crap untill it lasts. I just don't wanna be the dumb woman who gets cheated. I don't wanna get blind for comfortness. And so many times I just want to be myself. So at some point I've got to come that maybe I'm looking for excuses to fiish this up (honestly, I've done this before, so no surprises for me) So...Gosh I'm confused...... hope to get this resolved soon, otherwise I will never find the "right time" to do this. Crap, I haven't got a clue.
