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

I'm 20, he's 22. We met almost a month ago and have been on 3 dates, and our next one is this weekend. So far all of the dates have gone really well and he always says he had a good time. All we've done so far is kiss and make out. We haven't talked about if we're exclusive but I don't think he's seeing other people.  After this weekend, I have to leave town for almost 4 weeks, and I'd still be interested in continuing this once I get back.

How do I bring this up without scaring him away or thinking I'm getting too serious yet? I'm also worried he'll lose interest if we don't see each other for almost a month because he isn't really big into texting conversations either, so how could I hold his interest?
<bot>: Been going on dates with a guy for almost a month. Have to leave town for almost a month. Wondering how to ask him to continue this/not make him lose interest.
