Hopeless Romantic 😩

I am a complete hopeless romantic, I constantly daydream about my future relationship and what it entails but then reality hits... Situationship after situationship I find myself feeling so depressed because it’s not what I imagined. I’m a great woman, lover of all things literature, a college graduate, working for corporate America but my only downfall is men. I have been in a toxic situation for almost 3 years going off this fantasy. We aren’t together because this is his time to be free and make his money. I just feel so distraught because I want to be with him but ugh I don’t want to risk it. He says nobody our age is really faithful but I think he’s saying that too manipulate me into staying. Ugh I feel like I’m breaking my own heart because my dreams are not becoming reality and I’m wanting more out of this then what he can give me. Any advice?
