Boyfriend spending less time with me
I have been in a relationship with this guy for 8 months and he is 23 while I am 21. We used to get pretty well in the beginning, he used to want to hang out all the time but 2 months ago he changed to a full time job and things really changed. He started to hang out with his friends on Saturday morning and on Sunday morning. As a result of this we no longer hang out on fridays and on Saturday we are home by 1am so that he can wake up and hang out with his friends. Also Sunday when he goes to the movies with his friends he sometimes gets home at 1am but when we hang out together we only spend from 9 pm till 10pm on Sundays (since he arrives late because he finds traffic or so he says).
I have told him about this two times already and he says that I am right but he hates staying indoors and that he will try to be on time. Also when I tell him to go for a picnic with my friends on Sunday he does not accept and tells me to go with him for a ride instead and if I do not go he still goes alone.
This week he also took a day off to go play football with his friends at 9pm and I told him to hang out at around 6 but he instead went for a ride in the morning and said that he will not manage because he had to sleep before the game.
Also when we meet he always ends up sleeping and I tell him it is quite unfair because we meet like 5 hours a week maximum and he should not sleep at that time but he says he is too tired.
It really looks like he is bored with this relationship, I tell him we could stop if he prefers spending time with his friends but he says he does not want to stop.
PS he does invite me to go with him for the rides but I am busy with university so I cannot go and by no means I pretend that he does not go but I expect that he does find some time for me when I am available.
What should I do? He is pretty awesome and a good guy except for this thing.
