Brutally honest with boyfriend?

Not sure how to make this long story short but here goes.

I’m with someone who is a great person. We’re going on 2 years but we’ve hit some rough patches because of his ex gf, recent unemployment, his lack of future planning and poor decision making. When we first got together, she claimed to be pregnant which drove me and him apart. Shorty after we broke up, she claimed to miscarry. We ended up rekindling soon after.

A few months ago, we took some time away from each other because I felt he needed to understand himself better and get his life in order. During this time, he hooked up with his ex because it was convenient. Today, here we are again & she’s claiming to be pregnant again.

I’m trying to work things out with him but he won’t talk much about his plans for this baby. It’s like he plans on having that separate from our relationship. Which I don’t like.. I want to be excited and happy for him too.

Brutal honesty came when I told him he needs to plan better for his future. I told him he needs to take life more serious and be better about his health, finances, poor habits, etc. Since he asked to get back together and told me how serious he was, i also asked that he consider us as a unit when making moves. Basically to just be considerate of me as I am with him. I told him I can’t be with him otherwise. He seemed to be offended that I made such an ultimatum like that. But I’m fully aware that I’m lowering my standards to be with him. My patience is running thin. I do everything.. & I’m so patient with his progress as he goes after his dreams. He’s very supportive of me as well but I often question if love only is enough?

I hate giving up on people. Especially people I love. I’m guilty of falling in love with potential and not reality. I should probably run huh?
