my (21f) long distance bf (21m) is nonchalant, and it’s really affecting me.

my bf (m21) and i (f21) have been dating for 6 months (we've been talking for nearly 10 months though), and i've noticed that his lack of words of affirmation is really taking a toll on me. we've discussed this together before, and his love language is moreso quality time and physical touch — both of which are difficult because we are in a LDR. i've gotten upset before because i'm always the one who says 'i love you' (which i've begun to avoid saying first because it makes me feel awkward now) or 'i miss you,' or those kinds of affectionate sayings. he's told me that it's hard for him to say that kind of stuff outright, and that he does love and miss me but he's not really the type to verbalize it. i understand, but i'm someone who really loves hearing those kinds of things, and having someone give me words of affirmation, even if its something on the lower scale like noticing my outfit or asking about my day. since we're long distance, that's all we (or i guess i) have to rely on, so it makes me sad when he doesn't try to say something that he knows i would appreciate.

on top of that, we're going to be in the same city for three months working this summer. he starts his internship a bit after i do, and we have about two weeks of free time in that city before we're both busy during weekdays. he lives there, and i know he has friends/family he has to see and hang out with, but he made no effort to start planning a hangout, or asking when i want to see him. i had to initiate it, as i always do, and even then, he only gave me one day where he was free within that time period to hang out.

i don't want this to seem like he's a bad bf, he's very caring and attentive, and i know he loves me. it's just that he doesn't really think from my perspective, and i get scared that he doesn't feel the need to see me, which is scary. i'm not sure if i'm being too obsessive over him, and should let him do whatever? i'm also scared that if i bring this up again, i'm going to look like the mean one because i'm being mad at him for something he didn't intentionally do, or that i'm being too controlling by wanting to see him more and ask him to plan things or dates. in other words, he's just too nonchalant sometimes. if you can't tell, i'm an overthinker and someone who needs reassurance. i thought that he knew that about me (he definitely does) and so is the fact that he won't try to be more proactive in that sense a red flag? i really do love him, and i don't want to break up or anything, but i'm not sure how to approach the situation without playing the victim and being so self-absorbed.

TL;DR : he finds it difficult to verbalize affection and initiate that sort of communication, and even though i’ve said how it makes me sad, i don’t know how else to fix it, since it’s one sided as my sensitivity.
