<human>: Can you give me the gist of the text in a nutshell?

I've been seeing someone for three months, and it's been going well. However, he lives an hour away and is quite busy with his uni course (med school.) At the start he used to get in touch a lot and we'd see each other twice a week. However, for the last month or two we talk every other day and don't make plans in advance, and everything is fitted around him. 

I thought that this was because med school is demanding (I also have a very demanding career and work longer hours than he does) but have recently found out he used to schedule hour long skype sessions every day with his ex. They'd text and call (he's never called me) for most of the day, and he spent weekends with her. I've never been able to see him on a Friday/Saturday because he plays sports. 

Him and his ex were more long distance than us (she lived three hours away.) I'm struggling to understand why things are so different with me, and whether I'm even allowed to get upset about this??

I'd just really appreciate half the effort he put in with his ex. I asked him about being exclusive and he said we were, and I've also given him a couple easy outs saying if he's too busy for this I understand, but each time he has said no this is what he wants. 

Not sure how to proceed. Any advice appreciated. 

Also, he finished with her if that is relevant.
<bot>: He made a lot more effort to see/speak to his ex, and gave her more quality time. How do I deal with this?
