<human>: Can you give me a shortened version of the text?

We've been together for 4 years and I'm wondering if my girlfriend could be a lesbian.

We rarely have sex and when we do its usually me doing the lions share of the work. we rarely meet because our schedules are so bad but when we have time she doesn't want to do anything with me. She just wants to do her own thing.

She spends a lot of time talking about women she finds attractive. (Example: I found out about the Jennifer Lawrence thing because she kept talking about it.)

She is absolutely against moving forwards, we're essentially in the same place in our relationship that we were in 4 years ago. Every time I bring up something akin to engagement or moving in together she gets really pissed off.

I've asked her and she's said "I dunno maybe" and when I've pressed it she gets offended and says she isn't. Everyone thinks she is a lesbian and all of her friends have asked her at least once.
<bot>: I think my girlfriend may be a lesbian, do any of you have any experience with this? If you need to know anything else just ask but I can't really think right now.
