I always get sad when I see pretty girls when I go out

I am a 28 year old guy. Even though I have a bit of dating experience (just very little), I never had a girlfriend and I am still a virgin. I always got rejected when I asked girls out in real life. Or when I asked a girl I like to do something together, they were all the time busy so I ended up giving up after asking them quite many times. I've been also using dating apps since 9 years and only got 4 first dates that lead to nowhere. I didn't get a single like on dating apps since two years.

Yesterday I was working the whole day from home since my manager sent me tasks to do. After finishing the tasks, I went out to buy a fragrance I like. I was walking on the main alley of my city and all the girls there were so pretty and cute. Usually I find most of the women attractive. There were plenty of women a bit younger than me, around my age and older than me who were very pretty. However, it made me sad to think I will probably never have a girlfriend/wife like these women and most likely die a virgin.

Today I went to the pool and saw a very pretty woman around my age. She was not like a supermodel but she was very cute and I liked her style. She was sitting with her mom. And I felt sad again that I will probably never have a cute girlfriend like her. I don't know how will I find a solution to this problem in my life.
