communication issues

i have hard time communicating my feelings and needs. it's hard for me to like bring things that bothers me in relationship with my boyfriend and talk about it with him even tho i know it's the best thing i should do in this situation. the problem is that i feel like we are distant, we don't talk much and we don't give each other any affection, it's been like that for month, we like hold hands twice, but we didn't kiss or hugs, and we still say to each other 'i love you' sometimes but very very rarely. the problem with me is that i have tendency to mirror people, so if someone is distant so am i, i just feel like if he wanted to talk to me more i will, if he wanted to kiss me he will.

we are going to the same school so we see each other quite a lot and i get that maybe he don't want to be like one of those couples that can't take their hands off each other in school, which i get, im not like that too, but last month, we still sometimes find a way to show a bit affection when no one was there.

im scared that maybe he lost interest in me and just haven't find a way to tell me yet. it may just be that he doesn't have his car now, we were always closer there when we were alone. or maybe be he feels like he doesn't have anything to talk about w me anymore. im trying to see things from him point of view and i know i was bit distant too bc i haven't felt well mentally. i want to ask him about it but i don't have the courage.
