My SO says I'm getting too skinny...

I've been married for 2.5 yrs now and I'm at my lowest weight. we have one baby boy and at the very end of my pregnancy I was feeling so fat and I hated my body. after I had my baby I wanted to lose weight, but I was nursing so I waited until I was done nursing. at this point my baby was 2 months old. I started with really light workouts, but I guess I still went too fast because I ended up tearing the muscles of my stomach apart... My baby is now 6 months old and I started working out again 2 weeks a

go. I feel great. I feel stronger and more confident than I have for a while, but I have lost a lot of weight. I actually weigh less than I have for years and am even less than my marriage weight. 2 weeks ago I was fighting to maintain my body weight and was lucky if I stayed at 125. My SO kept saying he was worried I was going to fade away. well, 2 weeks later, having been working out 6 days a week and doing it pretty seriously, he asks if I've gotten down to 120 yet because I guess I'm getting skinnier still... I was very proudly able to tell him I'm actually gaining weight and weighed in right then at 127.2! I know it's not much, but I was so happy to see myself gaining and I feel better and stronger, but he still thinks I'm doing too much And getting too skinny... what do you think?

i have felt so ugly and self conscious to this point and i like feeling like this. I still don't like my baby stomach, but I'm scared to focus on that too much right now because tearing my muscles in my stomach was worse than labor. i like working out. But i also want to make my SO happy. do I need to tone down my workouts?
