Traveling with SO

Should I be a little bothered at the fact that my boyfriend invited me to a trip out of state but hasn’t bothered to pay anything for me? We are in a long distance relationship a little over 3 months. I don’t expect him to pay for everything but I’ve paid for my flight, my half on the Airbnb, the 2 day concert that we’re supposed to go to and I’m paying for my meals and drink. I just feel a bit bothered because he invited me to this trip, and he sure has enough to take random trips out of the country or last minute trips out of state. We’ve been dating a little over 3 months. Do men just not pay for small things anymore? Like a dinner or drinks? I’m just even more bothered by this because the last time I took a trip with him I paid for my way to meet him and my ticket to an event we went to and for the night to be horrible because he made an accidental call on Snapchat to this woman on Snapchat and her photo showed on the screen with her chest all out. Im not seeing any effort from him to satisfy me as his girlfriend.
