idk how to feel.

ive been with my man for 3 years and weve been living together for 2. to this day, i feel as tho he would leave the second he can, despite him saying he wouldnt. i cant seem to feel appreciated enough, pretty enough, "any" enough for his despite my efforts. im at a loss. im emotionally and mentally tired from it and idk how to deal. I'll let little things go all the time then the smallest thing can trigger me and next thing i know we are fighting about toes for some reason. he claims hes staying. he claims im the only one. i dont feel like hes cheating, but i do feel as tho he'll realize im not how he sees or portrays me as. im scared for when it finally hits him...
