I have been dating my boyfriend for a little over 2 years, and I pledged while dating him. He is a starter on the bball team and the only one of his home games that I missed was on bid day.
He has been 100% supportive of me, although he does tease me from time to time about an obsession with "piphi!!" (which he'll say in a highpitched silly voice).
I was very busy last semester between pledging and training for a peer counseling organization (10-6 every sat, 7-10 every tues night, all semester) but he understood what it means to have a commitment like that since he spends so much time on basketball.
He nags me from time to time about sorority secrets but so far I haven't budged
He didn't even mind when I took a guy friend to Monmouth Duo because he had an away game that weekend.
If he's worth your while, he will support you in this and anything else you want to do.
