Question about long distance relationships between a male (19M) and a female (18F) and the difference in religion

tl;dr Why would my Pentecostal girlfriend notify me of the hardships that come with being with her in the start of the relationship, and after knowing how hard it would be for us to live together and be accepted by her parents, why would she still want to be with me and keep me? She can't just do it for attention as she isn't talking to other guys, just me.

Not sure whether this is the correct subreddit to ask this but here we go. I have been in my first relationship, a long distance relationship since January ( so about 3 months). I have known this girl (who, very important, is a Pentecostal) since 2023 and she has always 'liked' me but I always assumed it was a discord crush and nothing else. In 2024 we had a thing for about a month where we said 'i love you' and played many games together but we never met and it ended because I had exams and couldn't give her as much attention as she wanted and it was my fault.

In December 2025 she was in a relationship with someone in real life, who had a girl best friend and admitted he cheated on her during the holidays, and they didn't end it for a couple of weeks. That's when she started talking to me and even admitted she slept on the call with that guy whilst talking to me (something which I am very very doubtful of, but she said it because the relationship was over the moment she found out he cheated).

During a year of not talking she said she missed me and looked for me in every guy she dated. Then in February we got together and it was fine. We've only had one chance to meet, she talked about wanting to meet in April 2026 and that she would come to me with her sister for a day (otherwise her parents wouldn't let her). This idea faded into nothing, I believe it's because she didn't want to spend money as she would go on holiday with her sister in their home country for 7 days.

However one thing after 3 months that still presses me is the fact that she still hasn't introduced me to her parents, whilst I did. Her parents are Pentecostals, and her mother especially doesn't allow her to leave the house alone. Until yesterday she didnt even get on the bus alone ever. I told her that if we want to make it work she has to introduce me, whether her mother will call her names or not. At the end of the day, it is her life and her partner and her parents love her, I doubt they would let disown her or anything like that.

I myself am not a Pentecostal but I am religious. I have recently started going back to church and check the 'bible' app daily because I want her and want to marry her. I think she also realises how hard it is for someone to change faith just for another person and that is not adviseable, but why would she still talk to me if she knew how impossible it would be to change something as big as faith, is she just using me because she feels nice to get attention? If she only wanted attention, she would be talking to other people as well, but she isn't, so she must feel something good with me or is just plain up using.

Everytime we talk about this she says her parents wouldn't let us be a thing (currently I assume) because of religion and that it will be very hard, when she realised I have interest for her she asked me 'you know I want to get married and that you will have to convert to Pentecostal' and I doubt she would ask me that if she just treated me as any other guy. Why would she still want to be with me if she realises it is hard and nearly impossible?
