Trying to stay strong ever day!

I always knew I was strong, but now being a FTM and expecting twins, and having their father in and out of the picture due to his own issues his trying to figure out I am starting to realize how strong I really am. At just 12 weeks I was left with no other option but to move back to my parents, I had been supporting both myself and my bf for the last year. With the news of expecting twins we knew it would be hard but knew we could figure it out. With the pressure of everything he crumbled and basically fled. I decided the best option for me and my girls was to move back to my parents for support. Shortly after he contacted me and we decided to give this another try but I said I was not leaving my parents home for something so unstable. I tried to help him to the best of my ability and drove 3-4 a week for 40minutes minimum depending on if there was traffic or not to support him as he tried to fix his life and get on his feet. He has no family here in North America and have always known this. Once again in late February the pressure of 2 girls coming in less than 3 months now just became to much for him. I went a few weeks without hearing a word from him and trying to stay strong for me and my girls. Finally he contacted me and I have since then decided to give him the chance to be around for our girls. I have told him that for me the relationship is no longer of any concern to me at this moment and I am just focused on giving these girls the best. My parents, sister and I are going thru an ongoing family crisis ever since my aunt ran some kinda of Ponzi scheme on my mom and took just under 100 000$ from her. There are so many times that I feel like I'm breaking and am so alone but I just keep telling myself to stay strong for my girls. God has a plan for all of us, and as long as I stay strong the benefits will outweigh the struggle. I still hope that he can figure his shit out one day and we can be a happy family. I do love him so much, and he tells me the same and I know he is being genuine, but I am just planning for today and tomorrow and trying not to plan the future so much because tomorrow is never promised.
