Just a every day thing

So I cant have kids and I'm only 27 year old but I notice when we go on a day out he stares at women pushing prams and I feel stressed about it but I keep it in as last time I mentioned it well it all went down and we had a massive argument today I noticed it's not just women who push there prams its actual women on there own with there husbands or even on social media I been with this guy 10 years am I not good enough nomore but then if I look I'm vain for looking at a guy who's walking a dog I am a huge dog lover I just dont know what to do I told him out of anger hes not Brad pit and needs to stop thinking hes a stud muffin ๐Ÿ˜‚๐Ÿ˜‚ I'm just really annoyed with it and it's really embarrassing for me especially when there a wife and husband and hes stareing at there wife I am.not saying walk with your eyes closed I'm just saying theres looking then theres stareing and giving your self whip lash
