Boyfriend is going through family problem and feels distant to me

Eve

Hello everyone, me (22f) and my bf(19) have been together for couple months now and we used to see eachother often because I wasn’t working but now I started a job and our schedules don’t really line up it’s hard to find time to see eachother and when he’s at work he doesn’t use his phone. We used to text somewhat a lot but couple days ago I felt him growing distant (less texting, him making plans with his friends but not me) and thought he just wasn’t putting in effort anymore so I told him how I felt and he didn’t know where this is coming from but since our schedules don’t match it’s hard to find time to see me and he doesn’t want to drive 40 mins to just see me for only couple hours after he works and is dealing with family problems he just wants to relax and if we had more time in our schedules he would want to see me more if he could. I didn’t know he had family issues before this convo and he doesn’t want to talk about it w me which is understandable. although I do feel really single and unwanted right now because he’s being distant (I understand this characteristic is something I am still working on) , at the same time I want to put down my feelings to support him. So I sent him some takeout the next day and have been texting him less to give him space but couple days have passed and all we really text eachother is Goodmorning not even goodnight. It just feels like he could go days without checking in asking how I am etc. but I know he’s going through hard time right now so is this normal? Is it normal to be distant from someone you love when you’re going through a hard time?? And if it is how should I go about this do I keep trying to support when It feels like he just might not be into me anymore?
