Is this a too “serious” view of relationships?

Yes, it is.

From a guy, to you, here are the only two things we want from you:

• Honesty from start to finish. Don't ever string a guy along if you don't know if he's your type. Find out quickly, reject him if he's not. Save him and yourself the frustration.
• Show him you love him. He needs to show you that he loves you. This ties into the previous point.

Do NOT (!!!!!!!) wait with a relationship until you're older. You're in university, you're 22, you're at your "last chance" to find like-minded guys. I've seen too many "where have all the good guys gone" articles from bitter late-20s university-educated women who can't date under their academic level. I don't know what your standards are, but those highly intelligent, good men are all taken when you're 25 and out of Uni.

finish my undergraduate studies and graduate school, have a career, possibly purchase a house and travel a bit

You're 22. You'll be at least 27 when you've accomplished all of that and you'll have no romantic network or prior experience you can build on. You'll start where most 17 year olds start, except the only men left are the non-educated, the divorced or otherwise unfortunate men.

If you ask me, you're too late to finding a relationship already. Hurry up and start feeling when your heart punds around certain guys, and start acting on it.
