How can I get my girlfriend less obsessed with me?

Ive dated her for 2 months and now she's starting to get obsessed with me. Granted I have a great personality and I'm extremely good in bed I make her sing like an American idol but all this greatness also leads to pain on my behalf. She won't let me go out and drink with the boys 3-4 nights a week like I used to and she texts me like 10-15 times a day and I'm getting tired of her a s s. Not only do I please her ually and make all her fantasies come true I am also very great to be around and caring but she is also interrupting my work outs and diet and the other day she tried to con me into going to her fathers funeral when I was planning to drink with my buddies. Should I just dump her clingy @ss?
