Hello, I’m a French citizen seeking to visit my long distance boyfriend (US citizen). We’ve been planning for a long time to close the gap for a couple months as we both want to be a normal couple and are tired of the distance. Have successfully filled in my DS-160 form alongside scheduling a B-2 visa interview, been to the us back and forth on an ESTA and have all the necessary documents asked but have a few questions concerning extra documents that could help me through the interviewing process such as proof of him inviting me to stay in the us (what exactly should be written in the letter), proof of being able to financially support myself (I have nothing as I will have just graduated college by the time of the interview) and proof of attachment to my home country (I don’t pay rent as I live with my parents, and do plan on finding a job in my field after my visit).
So yeah if anyone has any advice on what to do and what extra documents could be useful to me?

Like title says bf (M31) and I (F27) have been dating for 2+ years and long distance since the beginning of our relationship. We live in different states and have our own jobs so try to see one another every 3/4 months or so. He was over recently and left but I just can’t shake what I have discovered. One night as we were ordering some food on his phone an only fans subscription email popped up. Was instantly filled with rage and disgust and bombarded him with questions which most were answered. He had been using it on and off before we were even dating and would use it for a week before deleting his account and not using it for another 6 months or so. Furthermore was earnest about everything and had never dm’d emotionally or anything of that matter to the creators on the app and viewed it as porn and nothing else, alongside mentioned it not being any different than a Brazzers subscription.
Now I would like to say that as we have been doing long distance since the beginning the consumption of porn is really not a problem for me, as I myself watch it without putting a thought into it. My problem though is that it was specifically OF an app that is notorious for being evil and capitalizing on people’s misery, money shortage and loneliness (ntm it being straight up prostitution) and we have previously had conversations about how I felt about the app and its users. Also swore to me he never used it when we were physically together and promised there on to never use it (didn’t really give him the chance to go back on it as I have made it clear I would leave).
I feel absolutely blindsided as he has been a very honest and earnest person, is an exceptionally good friend and has never given me any reasons to not trust him, has opened up about 99% of his life, past exes etc…
So yeah wanted to have some some insight on this situation. Has anyone else been in his or my situation?
