What I want from life

So it is time to figure out what I should be in life regarding becoming a family-man, husband, son, and father. I should be caring, not yelling all the time which I have a tendency to do, I should listen to concerns to others and try to help them and be there for them. Being a husband is difficult because I let my self down and my wife but that has to change, what I believe is being the best soul mate. Instead making excuses listening to my wife advice is the only way I well get far after all she is my better half more like 99 % percent. I want to treat her nicer I cannot forget what I have done but I sure as hell have the opportunity to make her life easier. I want to prove I love her becoming more reliable for whatever duties I can take off her hand so she is less stressful. This is her final semester so I definitely do not want to screw it up by giving any type of stress. I am fully accepting I have major major major problems. I also have to admit it is her decision to be with me no one is forcing her she loves me and that won't change and I love her back that won't either so i want to work things with my wife so we can be a team. I need to better son taking care of my mother and being nicer to her as well; Hopefully with my wife in my life things well be good so the both of us can work to together to take care of family. My daughter needs me hope to spend some time she is picking up bad habits and I want to fix myself so she can start doing the same before she ends up like me and of course. I do yell at her swell which I have reduce but I want continue and try to be around and over a good positive role model. She will most likely look up to me and if I want best for my child then it is time I show it. I think in marriage disappointment and mistakes happen long as I am truly sincere honest and trying to work on them my wife will be there for me. She isn't leaving she is staying for good and really without her I would be dead cause I am hopeless and would have no direction. If I fail I will try again, she will get mad but important thing is picking my self up and keep trying to achieve my goals.
