<human>: Can you provide a brief rundown of the text in within 3 sentences?

GF went to uni for her first year, I knew I would be uncomfortable with her spending time with other guys and the attention she would receive. Suggested we break up before she left but she was adamant she wanted to stay with me as I am her first love.

Now she is at uni her attitude towards us/me has lessened as she has other things keeping her interest. She also smokes weed and has done since I met her, I however don't smoke (but don't mind that others do).

She now spends several hours a day with a guy she met at a party. She smokes weed with him alone in her room. She talks a lot about her other friends there but has not mentioned much about this guy even though he seems to be her closest friend there.

I am concerned that she may be attracted to this guy but is conflicted because she believes she loves me and is now crossing emotional boundaries. I have told her it makes me feel uncomfortable but she has yet to change her behaviour. Possibly because of her naivety due to age difference.

Thoughts?
<bot>: LDR GF gets high alone with dude who shows off his tattoos to her. Makes me uncomfortable. She doesn't seem to understand or change her behaviour.
