My boyfriend (m20) and I (f18) have been in a relationship 8 months. The first few months were amazing, thoughtful dates and so much time together.  
Until about May we would see each 8-10 times a month. It started decreasing, by July we only spent 2 days together that month. He lives 2 minutes away, and works 5 days a week. It's been 11 days since he came over on one of his days off, it'll be over 2 weeks by the next time he does. We've had 2 talks about this, he listens but things stay the same.  
I got my car last week and was really excited that I'd get to see him more. On Saturday night he asked me to stop by, I did and we were intimate. He immediately handed my clothes and hinted for me to go after, I tried to not overthink it as he had work the next day and it was night. I decided that on Tuesday I would take him on a surprise date somewhere he'd been wanting to go, he told me earlier that week he had tuesday off.  
During one of our talks (last June) | brought up that we never go on dates anymore, he didn't give a very clear answer but made multiple comments about the cost and money stuff. I told him even if we go to a free park and just hangout there, i'd be happy. It's not about the money, and I offer to pay at least half (often more) of all the dates we have. I'd also like to say, he's constantly dropping money on his Pokémon collection (often 150-500 dollars a week). I totally support his hobbies, but it's just not true that it's money alone stopping him from going on dates.  
On Tuesday he decided to stay home again, so the date | planned just didn't happen. He said he just  
"Slept in, haircut, played with the cats and dogs, watched a video with my mom" and he was also online on discord from morning till night (possibly gaming with people?).  
Wednesday night he asked me to come over again, and it went basically the same as it did before but he let me stay longer after. I planned on talking to him and expressing that I was hurt, but the attention from him felt so nice I just gave up. I'm super disappointed in myself, but | also don't want to have to feel this guilt just for being intimate with my boyfriend. Am I asking for too much or is something not right here? Any advice on how to handle this situation would be really helpful as well, I struggle with conflict a lot (hence why we've never argued). 

PLEASE take me out!
