<human>: I have been with my boyfriend for about 8 years. We are very compatible with our beliefs, ideas and other important stuff. We both want to be together (as brought up by both of us various times). The problem is not the relationship per se but my lack of discipline and control in my own life.

We are both studying a career in science but I am half assing through it and life in general like there is no tomorrow. I have never been disciplined and/or other good qualities that help one have a stable life. I am studying what I want, the problem is that avoid problems when they are presented to me. I havent had any self control for a long time and I am thus failing very badly in school. In other parts of my life I have gotten better but still have some work to do. 

This semester I am failing all subjects again, it is ridiculous. I have thought about a solution and these past weeks I have actually gotten around to studying and feel like like I am approaching an actual solution. This studying is not going to be enough to save the semester and when I get my grades back this is going to probably cause a break up between me and him. This has happened many times. I slack off, I fail everything and say I will change very convincingly and some times he stays with me, sometimes we break up for a while. I think that what I do is very wrong but this time I think I can actually change. 
 
How can I speak to him about this and make it seem like the real thing this time? Its not to say I have lied in the past about wanting to change but this time I feel like I have gone deeper in to what the problem is. I understand we might break up and he has told me that when I change he will be waiting to be back with me, but I think we can make it work together this time. I am sorry if this is written in a confusing manner. I will answer questions as they arise, thank you!

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: I am half-assing my life and I want to assure my boyfriend he can trust me to really change in order for us to stay together.
