Welcome Chanmichelle,
I know what you mean about how love crept up on you. I am not sure how I gained the weight (accept the obvious by eating), but feeling "comfortable" in a relationship and loving to cook/eat, did not help matters. I have taken the bull by the horns and will win this battle. This website is great and you will find a lot of support groups. Just find something that works for you.
My goodness the homemade mac'n'cheese with pancetta sounds heavenly. Tonight we grilled some fish and zucchini. I have made major changes to my diet and I workout, workout and workout (this is my new addiction).
I wish the best to you in your journey. Be strong
