LDRs only work when there's constant communication between both parties. Having a clingy gf who needs to hear from u 24/7 won't make this rship any easier. It also seems like she has anxious attachment style. The more u push her away, the more clingy she can be.

If u have sat her down n had an honest discussion with her abt the importance of yr job n that u're still into her even though u seldom text her but she still doesn't understand, then I don't see this rship going anywhere. It' only works if she stops being clingy by making herself busy like getting new hobbies or u find another job.
