My girlfriend and I have been dating for almost 8 years now. We have a pretty normal relationship not really a lot of fighting or disagreement. She's amazing and i love her and don't question anything she's doing. For the past three weeks beginning today she has been extremely distant though. She's started sleeping on the couch at night, pretty much doesn't come around me during the day except for a hug or kiss maybe once before she goes to work, and the contact between her and our pets (rats {they live in the same room as us}) has diminished to the same point. Her routine after she gets off work at night is usually to come home and lay in bed with me. She's been working with her bestfriend/manager for a couple months now and she carpools with her so she would usually get off around 11 and be home around 12. Around a week ago she started staying out late till about 3-4 in the morning with the friend and started coming home drunk; just for context her friend also has a very young child to take care of. It didn't seem like a huge deal the first time but its been happening more frequently. She's started coming home to in different outfits then what she left for work in, and I just recently noticed she's also been taking shower supplies to work as well. I really started to question what was going on when, about a week and a half ago she asked me if she could go help this friend fill her tire with air at 1 in the morning (just seems a very weird time and doesn't make sense to come pick someone up if your tire is low on pressure already). I personally don't understand how her friend has the time to take care of herself between work, taking care of her child, and carting my girlfriend around all day who knows where. I don't know why it seems like she's avoiding me, maybe she's not, maybe I'm just thinking too much i have pretty severe ocd so i do tend to think on things way more than I should.
Guess im just not sure how to confront her on this or even if i should.
i haven't had a chance to talk to her yet but I've talked to a couple of my friends that have her added on tiktok and snapchat. She's started posting videos in her bra grabbing her breasts or in her underwear and its very obvious. She also says in her bio she's bisexual and its not on any of her other social medias. A couple months ago i had heard from her that she was talking to other people about making a sexy tiktok or Instagram. I found out from trolling a guy off of her snapchat that was trying to get in her pants.
**TL;DR; : My girlfriend of 8 years has been sleeping in a different room and staying out till 3-4 in the morning and comes home drunk. She has weird reasons for leaving the house and things just dont add up. I now think she's cheating but don't want to confront and start a fight.
Im not sure myself. I just want to see if it sounds like cheating to anyone else. Or if others think her behavior is normal. I can pretty much tell at this point that shes probably not interested in the relationship anymore.
