Hi Aqmell,
Most of your interaction with her has been over text.
Both of you haven’t really been out on any dates.
As a result, she may be worried about completely opening herself up to you emotionally.
Thereby, she’s being guarded with her feelings.
Given how young and inexperienced she is, as well as the fact that she is from a conservative family, she doesn’t really have another relationship from her past that she can use to help figure out what her true emotions are for you or what they could become.
Your best approach may be to continue taking a keen interest in getting to know her during this time.
Communicate with her in other ways besides texting.
Do video chats with her and call her on the phone.
This will make your interaction with her more personal and will also give her a better understanding of your personality.
When the current outbreak is over, ensure that you go out on frequent dates with her.
The more that she’s around you physically, the more she’ll be able to determine whether she feels safe and secure around you.
Knowing that she feels safe and secure around you will often give her more of an incentive to open herself up to you emotionally.
Once she reaches a point where she’s comfortable opening herself up to you emotionally, she will have a better idea on whether you are truly someone she would want to marry at some point in the future.
