<human>: Any input is appreciated.  

The details: 
My age: 33  His age: 30  Both male.  Friends for over a year.
We hung out the day before my birthday.  Day of my birthday, texted him to see if he would like to join me for a few beers for my b-day (a 3.5 hour notice, mind you) and said 'don't feel obligated because I will try to organize a little hiking trip in July'.  He read the text and didn't respond.  

Hours pass and I ask him his plans for the night and to my surprise he said he wanted to stay in and plan out his next two weeks.  See, he wants to get all his ducks in a row before the arrival of a girl he thinks might be 'the one'.  It is Saturday night and my birthday.  

I told him I was "a little surprised you didn't respond to my text" but haven't passed judgement on him or said anything yet.  He is a very good friend and I don't want to damage our friendship by saying something without carefully considering the circumstances.  Would appreciate your perspective, reddit!

Can you summarize the given text in a few sentences?
<bot>: Friend ignored my request to hang out on my birthday so he could prepare for the arrival of a girl in two weeks.
