Girls, I don't know what's going on with me. I've become insanely jealous of my husband, checking his phone and so on. Although there's no reason for it, and I'm always in touch and know where he is. But sometimes it hits me like that, that nobody understands me, that I just lie coughing, while there are beautiful girls everywhere in shape. I understand that if I continue like this, he will really run away), sometimes I overdo it. I think I'm already bothering him with questions like "Are you sure you love me?" ?and so on. I hope this will be harmonious after the birth? Who has experienced this, how did they prepare themselves?
