"Single", 26 and Trying to Get on Track

I don't know about everyone else, but I am 26 years old, and at this point in my life I thought I'd at least be married by now,. Life did not give me those lemons very quickly, but that is okay. I finally learned after an awful break up and "lifestyle" change 15 months ago that you cannot always plan a picture perfect life. Currently, I am with an amazing person who treats me right. Because of him, I have learned not to settle less for anything I deserve, and I have come to the conclusion that I deserve to feel great about myself. Now, before anyone jumps to conclusions: No, he does not call me fat. No, he doesn't drop hints about my clothes, weight or anything else that could bring my self-esteem down. He tells me I am beautiful everyday. I was the one that brought up losing weight to him and he grew worried that I thought he thought I wanted him to.

The truth is: I want to do this for me. I have a habit of looking towards the future a lot. After finally meeting the man I want to spend my life with, I have thought about the house in the country...and the kids. I am 5 foot 1 weighing in at 150 pounds. By the time I get pregnant and have a child, I don't want to be weighing in at 200 pounds if I can help it. I also want to feel good in my jeans and not have to hide my gut in a hoodie like I do now, or have to buy a size bigger because my gut doesn't fit in my jeans, and because I have no butt to fill those jeans my rear sags. I want to look in the mirror and not feel ashamed of how my chin looks. I am tired of feeling self-conscious about my body. I want to not only look but FEEL absolutelly beautiful on my wedding day.

My goal currently is to lose 20 pounds by July, which would put me at 130. I would like to weigh in at about 120 pounds, but 130 is okay. In high school I started freshman year at 105 pounds, which was too small. I graduated at 115 pounds, which was great, but I remember feeling my best at 120. Does anyone have any helpful exercises to burn the calories and gain the muscle that I can do at home in my apartment during this cold weather? Really need some help and support! Thanks everyone!
