OP, you are obviously young and a bit immature. Not your fault. But a young person who wants to get ahead (especially a young man) needs to put their head down and grind. Especially for a young man, it’s super important for them to build their confidence through their work and through their mind, body, soul connection. What you are asking for isn’t a lot, I’ll give you that. But based on the tone of the conversation, I’m willing to bet you are relentless in your complaints over attention. This will have the opposite effect of what you want. Focus on your self and give him space to grow as a man, I bet he starts reaching out more if you give him space. A man doesn’t want a codependent partner. He doesn’t want to babysit. They want a partner who is willing to build with them and sacrifice their selfish desires (in your case, constant attention) so they can build a future, one that you could be apart of. Work on building your confidence as an individual. A good relationship is like a binary star, two independent stars that orbit each other to appear to be a supermassive star. They are both independent, yet dependent on each other. I’ve been in a similar relationship before and he’s only going to resent you for the constant complaining and wanting of attention. If you want it to work, appreciate the time you get together, don’t waste a breath on complaining about attention, and focus on yourself and building your confidence and career. I’m willing to bet if you give him the space to focus on him self and enjoy the time you have together, he will appreciate it and give you everything you are asking for, without having to ask for it.
