This is / was my issue with work. I (used to) invest my self a lot in my work. I didn't count the hours, was underpaid, was doing 4 times more than my position described. And I was promised a lot of things! I was thoroughly thanked by my immediate management. I was promised a raise and a promotion. But ultimately they always expected me to bend when my suggestions didn't fit with their immediate vision. I left (and did they cried about it, telling me I was wonderful etc.), and I landed way better jobs, way better paid. I figured that I was the problem, for accepting those conditions. Why would a company want me to work less for more money? When I'm already working so much, for so little. I stopped doing that. I refused offers because they couldn't offer enough (like expecting a lead dev / senior dev for the pay of a junior), even if I loved their product or company! So my advice is leave. And don't even look behind.
