<human>: Can you give me a shortened version of the text?

I am a 20 year old female, he's a 20 year old male. Like any relationship we've had our ups and downs including one very short breakup after a long summer break (we are college students) and a stressful first week of classes. I love him so much. We've been dating for 22 months. 

We just saw each other for the first time after a month apart the other day. We talked on the phone sometimes during the summer, but communication was never his strong point. 

The day after our first day no longer being long distance, I got shocking news my dog had to be put to sleep. I told him I could really use a hug, but he never showed up. This kind of hurt my feelings, although he showed up the next day and apologized for not being able to see me. (He did have to work a good chunk of the day).

However, when I saw him he seemed really really sad and down. I had gotten a lot better overnight and was beginning to accept the loss. He told me he had a lot on his mind. I asked if he wanted to talk about it. He said, "It's personal I don't want to talk about it. I've talked to ___ and ___ about it". 

I'm not going to lie. It bothers me that he won't talk to me, but I also am more worried about him. Also, I have no idea what is bothering him....it could be he's questioning our relationship, worried about school, stressing about who knows what. I want to be there for him. I also would really like to spend time with him before school starts on Monday after over a month apart, but he's either working or doesn't want to do anything.
<bot>: How can I be there for him when I have no idea what's bothering him and he won't talk about it?
