I think the only real problem would be to pursue anything deeper than a platonic friendship while at uni if you have no plans to continue afterward. If you think you can really maintain a friendship with him without getting too involved then I say go for it but if you truly think it's not possible for long term, after uni, then don't let it get past the friendship level.

Only allow it to get deeper than that if you see a future with this guy. otherwise it will probably end up in a situation where one or both of you end up being very hurt and have a lot of regrets.
