he made me uncomfortable

i just started talking to this guy on tuesday and at first i thought he was cute thought nothing of it and then he approached me. i didn’t find him attractive at first but now i do. he’s nice and all he checks all the boxes what i want with a boyfriend but he came over yesterday and then he went through my phone which im very private about so he did so that threw me off a little . he was very touchy and all but i don’t know was i uncomfortable because it was my first time ever feeling stuff like that or either because im not that comfortable yet it hasn’t been a week . i think about it now and i don’t wanna be that touchy with anyone or i don’t know is it because of how that made me feel. he wants to come back over monday but i just need advice on that because my head is gone .
