Problems with boyfriend

Don't know what to do anymore with my kids father. We have two kids and have been together for almost four years I have no trust since he lost that along time ago and although I want to move past it I can't because he always has let me down and also he hasn't asked me to marry him and mind you he's 32 I'm 23 he asks so much from me and I feel he doesn't deserve it I gave him so much and he took me for granted so why should I give him my all now I'm stressed all the time I need help

Your very young and should not be treated this way. I dont't know how he broke your trust but I can assume. Technically you are a single mother, and young get a grant go to school if you haven't already gotten a degree and move on. You have given him two children and he can't commit to you and already your 9 years younger than him. He is probably looking for someone younger. Trust me.....you will thank yourself in 10 years if you focus on making your life with your children without him.
