Sort of new and not wanting to go alone anymore

I have had the MFP app on my phone for a long time now but I've only used it intermitently and will interesting results. I am in a relationship with a man who loves me the way I am but I am uncomfortable with my current weight. I'm 5'5" and 230 ish pounds it's not that I think I look bad I just feel uncomfortable if that makes any since. Another reason for this journy is I have 2 kids and they are wonderful little girls I don't want to be the overweight unhealthy mom telling them how important it is to be healthy I don't whant to be an example of what not to do I want to be the example of what to do. I recently quit smoking (it's been a month) and I am doing everything I can think of not to use food to substitue that habit. The big problem is I am and eater I eat when I am happy I eat when I am sad I eat when I am mad about the only time I don't eat is when I am super stressed out but that is almost worse because then I forget to eat the whole day untill I notice and then I eat everything in sight. my Boyfriend seems to be able to eat what he wants with out gaining weight and even though he is super supportive (in his own way) it comes across more as you can't have that rather than you shouldn't or even hey how about this instead (yes I have talked with him and he is trying) I am just not sure if its the way he is saying it or if I just feel resentful you know the don't tell me what to do syndrome.
Anyway I recently started a new job so I haven't had my phone since my boyfriend picks up the girls and then me after school and work so He has the phone during the day and I am trying to be really committed to making a change and well if one were to look at my diary it's really sporatic and I feel I need more support. That is what led me to the website I wanted to keep up with my diary as I was consuming things and I promised myself that I would report no matter what I ate so if I broke down and had something way off track I wanted to be able to report it before I can talk myself into pretending I didn't eat that extra 2 biscuits with butter and marmalade. So anyway I also am a bit of a rambler as is obvious I am sure. I'd appreciate any adds and any support anyone wants to throw my way.
