I was in your position 18 months ago.
In December 2020 I met someone and we were both in love by October 2021. We spent hours talking, playing games etc. Sometimes we video called, sometimes it was just text. We were aware of the challenges surrounding long distance, but we both promised to meet up regularly and that if we did break up, we would remain friends.
We broke up 3 months ago. She had been lying to me the whole time.
She had some fairly significant family problems, that I was not made aware of before we started dating. These problems made us meeting up almost impossible, or even just having an online date night impossible.
She also never intended for us to meet up. She just wanted experience dating a man her age, before actually dating someone in person (she had only been with women before me). Sure enough, 3 weeks after we broke up she said she had moved on.
She also has completely backed out on the staying friends aspect. She kicked me from all of our mutual group chats with mutual friends, whom have all left me since.
She came on a holiday to the UK and stayed 2 hours from my house, but we still didn't meet up. Whenever I tried to go there, I was shut down.
We broke up because distance was too hard for her ...
LDRs can work. I was completely invested. But make sure your partner is too. LDRs are amazing things and incredibly rewarding. Just don't get stuck like I did.
