Do you think my girlfriend could be having sex my new next door neighbor?

Hi all! I think I got an infidelity problem going on with my steady girlfriend of 2 years. Ever since my new next door neighbor moved in, she's acted very strange lately. My new neighbor's a nice guy. He lives alone like me. I don't know if he's seeing a woman or not. He invited my girlfriend and I to have dinner with him the first week he moved in. I noticed how she started asking him lots of questions at the dinner table, mostly private questions if you know what I mean, and she mostly ignored that I was even at the table. Before he moved in, her and I had sex at least once a day and I didn't even have to ask for it because she always wanted it. She hasn't acted affectionate or sexual around me lately like she used to and she definitely hasn't wanted sex over the last two weeks. She calls me less and less on the phone and a lot less IMs. I came home from work early one day from work and I saw her car parked outside his alley way. I called her cell but she didn't pick up. I looked outside the window about ten minutes after I called her when I was in my bedroom to look outside the window and her car was gone as if it has suddenly disappeared. My next door neighbor's around my age, in his late twenties, but he's about 6'5'; and about 275lbs. I'm only 5'11'; and about 150lbs. He's definitely fat but he's just big. I just don't want to get into any fights or have acts of violence with this guy. My girlfriend has denied going over to his house. I also searched her purse one day last week and I found something in there I never found before. I found a few condoms in there. Her and I have never used condoms because I had a vasectomy before I even met her. When I asked her about her car being outside that one day, she said it wasn't her car and she was at work. I called her workplace up later on in the day and her boss, who's a good friend of mine, said she took an extended lunch break during that time on that day. My house is only about 10 minutes away from where she works. Do you think my girlfriend could be having sex with my new next door neighbor? If you think she is, what should I do? Any answers would be appreciated. Thanks!Do you think my girlfriend could be having sex my new next door neighbor?
Sh!t. Your girlfriend may be having an affair with this neighbor of yours. Based on the details you gave, it seems like all of these events are pointing in the direction that your gf is doing it with this other guy. It may be overwhelming to think that your gf of 2 yrs would chose some other dude over you, but if you really, and I mean REALLY think that she's having an affair, then you have to confront her about the situation.



There could also be the possibility of paranoia. I mean she could have been late on her lunch break, or she could of been out shopping when her car was gone.



There's a 50/50 chance she's cheating on you. You just have to communicate with her and if she's cheating, and I mean IF, then maybe you should take time apart for awhile.Do you think my girlfriend could be having sex my new next door neighbor?
What more proof do you need? the condoms should have been enough. Sorry.
WHy whould she be carrying condoms if u had a vasectomy done! just doesnt seem to add up..

unless teh condoms were given to her somwhere which doesnt make sense..

I am sorry but it seems like u may have some issues with her..
Dude Hes So Bangin Her Lose The slut
Hate to say it but it sounds like she's got somethin going on and not with you.

Better handle up on your bussiness.
Tell her if she's not gonna give you the truth it's over.

Sorry.
Hell yeah she's sleeping with him I'd leave her and beat his *** but that's just me, since you don't want to use violence I'd just leave her and find someone else! There's plenty of fish in the sea, go out and have fun not all relationships last forever i know! I've been cheated on too by my ex that i was with for 2 years and i thought everything was fine but **** happens so get out and find a good trustworthy woman!
