I feel like I lost my dignity and I feel ashamed. Not feeling worthy of real love and be taken seriously

I’m 26 and I was dating a 37 years old man. He belongs to my friend group and he has shown interest in me last year but we only started seeing each other romantically last month. We went on 6 dates. Although, I was feeling a bit confused about his intentions and his dating history (never had a long-term relationship), I decided to continue because my friends told me he’s such a great guy and he wouldn’t just use me because of his reputation in our social circle. Sometimes people just have different communication styles and are a bit unlucky with relationships. He never texted a lot but he would text every other day.

In our last date on Sunday, I went to his place because he was packing his bag to travel to his home country for 3 weeks. I understood he was busy so I wasn’t mad to him for cancelling our previous plans. We got intimate (grinding, kissing, he did oral sex on me and I gave him a handjob) and he came on my ass. We were intimate like this before but it was the first time I made him cum. We cuddled and he fell asleep in my arms, I thought it was a sign of emotional connection. He would look at me and smile too like he felt affection towards me.

I left to my home and he messages me to ask if I reached. I reply that yes I arrived home and he just reacts with a kiss emoji which is unusual of him. After that, no good night message, no good morning, nothing. He just texts me next day to tell me he landed just because I asked him to. I know he’s busy visiting friends and family but I’m starting to think this is so inconsiderate and disrespectful. He knows I’m a virgin so I know it wasn’t a big deal for him but it was for me. I think it’s reasonable to expect communication if you’re dating someone for 1 month and you just got intimate with them.

Today I posted a picture of myself on social media, he reacted with heart eyes emoji and that’s it. No call, no message, no nothing. We have plans to meet each other when he comes back but will he just stay silent for 3 weeks? I’m feeling so embarrassed and like a prostitute. I thought this man had more consideration for me. I don’t even think I’m worthy of trying to date again and look for a serious relationship for the fact I put myself in situations like this. How to overcome the feeling of disappointment and shame?
