It can be a red flag, depending on the girl and your own capabilities. My last gf was like this. Obsessively. She had a lot of issues but it got to the point where I personally dreaded seeing her because I was so tired of her clinginess. That’s just my story though and maybe your girl is different.
I’m not really sure why people are straight up downvoting people who maybe bluntly said this is a red flag, I’m gonna say what nobody else is saying though and say that she probably needs therapy and that if you feel like it’s causing tension in your relationship to be dating someone who sounds like she’s pretty anxiously attached or stuggles with insecurity/trust issues then reconsider the relationship from that angle and what your boundaries are.
