Do you think I'm doing the right thing???

So my boyfriend and I have been TTC for 3 years now. We've been together almost 4years. Since we have been together I've gained about 30 pounds but was on the thicker side already. So this year I've decided I want to get back in shape. Like really do it this time. I have one daughter who is almost 9 and he doesn't have any kids. Well I just told him the other day I want to take about a year break from TTC so I could lose weight and get healthy again. He doesn't understand why. He said why not have a baby and then lose weight. Obviously it's not happening like we would like so I figured if I was more healthy then it would be easier to get pregnant. When I got pregnant with my daughter I was about 70 pounds smaller. Any ways, do you think I'm doing the right thing? I'll be 30 in 7 months.
