Situationship help 🫠

So I’ve started seeing a guy, we talk everyday for over a month that alone has made me catch a little feelings (I’m a cancer okay💀) he’s in the military and just found out recently that he is being sent to Korea in a few months so we agreed on nothing serious since he will be leaving soon the thing is he does things that I’ve never had before which is literally bare minimum things but no guy has done it for me like when he picks me up or takes me anywhere he will open the door and close it once I’m in and he will cuddle me literally all night and i thought at first it’s just to lead to sex (which is fine we are basically sneaky links) but even after sex he will cuddle with me all night even in his sleep i woke up to him kissing my cheek softly and looked into his eyes and he smiled he also was rubbing my back when he thought i was asleep and kept kissing my forehead softly randomly during the night after i would roll over towards him. He bought me food and took me home and i offered to pay for my own and he wouldn’t let me i also offered gas money and he wouldn’t let me, his friend called him asking where he was and his response was “I’m with ole lady” which is a saying in the south meaning someone’s gf/wife i didn’t say anything but smiled. When we have sex he will get right in my face staring in my eyes and smile slightly, after sex he will grab a towel and wipe me first before caring about him self. He was trying to show me something this morning on his phone and I seen he has a picture of me in his camera roll and I’m not to sure why but i didn’t ask but the picture was of me and my bff but he cropped her out the picture maybe to show his friends? I already met and know his close friends so they already know who i am so i don’t know who else he would’ve sent it to. I’m just getting mixed signals from him we agreed on nothing serious but we act like a couple together and I’m scared to fall in love with him because he’s leaving soon
