<human>: Could you distill the essence of the text into 1-3 sentences?

I'm a 20 year old male in my sophomore year of college, in a relationship with a 21 year old female, a junior in college. We have been dating for 8 months, and have been as intimate as possible without intercourse. She has anxiety--for those versed in psychology, her attachment style is Anxious-preoccupied, and mine is secure--and is very much in love with me.

I consider myself religious, and as such have lately viewed our sexual services to each other with contempt. It was fun at first, no doubt--I just find myself wanting less of it. We have a good time with each other playing sports, watching shows, and being lazy together.

Lately, I have been wanting to spend less time with her, and more time with friends. I also have been interested in other girls to a degree. For instance, I went on a retreat of sorts where thousands of Christians attended; I usually meet up with many old friends, and have a great time. There's this girl that I meet regularly on these trips, and we talk freely about spirituality--something I can't do with my current girlfriend--and it is always refreshing. She is also very attractive. This is just one example of multiple similar experiences.

I love my girlfriend, no doubt. I care for her, I find spending time with her enjoyable. I'm just afraid that I'm not in love with her. She says, "I love you," to which I reply, "I love you too,"; I feel as if I should add, "but I'm not in love with you." Lately, I've considered breaking up, due to the fact that I feel that there are better options out there for my spiritual and mental health. I absolutely do not want to get married--or lengthen a relationship--because I was too worried that the breakup would bring their anxiety into overdrive, and damage them mentally. I'm her first everything--I've had multiple girlfriends in the past.
<bot>: Is this a lost cause? I am afraid of being trapped in a dead end relationship because I don't want to back out for fear of heartbreak on her end.
