Am I overreacting ?

My bf’s ex recently had a baby and she sent him a couple of pics through IG. He knows I have an issue with her and he never told me she had a baby. I saw it on her IG recently. He downloaded a pic of the baby from IG since September and still has it. When I asked him why he said it was out of respect. I’m 11 weeks pregnant right now and I’m not sure if I’m overreacting due to hormones or is this something I should really look into.

Another thing is when we had an argument about him downloading and keeping the pic he said she asked why doesn’t text her anymore and he said it was because of Me. Wow. I know she still has feelings for him I’m just concerned he still has feelings for her. What do you girls think?
