Would this be going overboard? 10 pts best answerr!?

OK so im 20 and my boyfriend is turning 21 this year (may 11) so its soon! we've only been together for over 3 months but i have very strong feelings for him and he has very strong feelings for me too. i want to get him a good present for his birthday and i know he likes Kid Cudi and Cudi is coming to Milwaukee this summer and i wanted to get us tickets. he already took me to a Wiz Khalifa concert AND paid for both of our tickets, so i was wondering if it would be too over the top if i bought two tickets for Kid cudi (theyre around 200-300 $$ for both tix. for goood seats) would that be over the top since we've only been together 3 months? i dont wanna go too crazy but hes so sweet to me and i know he'd really like it. what are your opinions? please be honest!
