PLS HELP!

18M i am in a somewhat relationship with someone. i say somewhat as we are not technically together due to the reason i will be leaving for very long periods of time at my dream job (Army) which i completely understand. recently we have started becoming intimate. i am her first i have been with previous people before her but thats not relevant in my opinion. when the first time came around she initiated everything and i was always asking “are you sure” “are you okay” all the reassuring and comforting stuff as i had experienced something tough that makes me quite unable to understand enthusiastic consent (i need to hear verbally yes or no) during the whole experience she said she was okay and from my perspective she enjoyed it just as much as me. fast forward a month she is currently on a vacation and a video that she reposted appeared on my fyp saying “he didn’t force me but he kept asking till i said yes” i not once can i recall me begging or nagging her about it. might i re add the times we did do it she initiated it all. im quite strung up and now i cant sleep because all i can think about is whether i did something wrong or if i did do what the video said without realising but yeah im quite lost. (p.s i have my final fitness test for the army in the morning and now its 1am and i csnt sleep at all) pls someone just say that im looking too deep into this and i dont want to bring it up with her until she’s back which is a week away but frankly i cannot go a week with the thought that i made her feel that way. hope this makes sense im typing as i think. My main question is WHAT DO I DO AND IS IT MY FAULT?!?!
