This brings me to now. After having been through all this, I feel that I need to make a decision. The burden of my thoughts are interfering with my studies, and other aspects of my life 
I feel like I know what I should do, but I am hesitant to act rashly. I know everyone is different and would handle things differently, but I think I could benefit from the perspectives of others. For those of you who already shared your stories, I thank you.
I want to be with her because I do love her, but I’ve never felt pain like this before
I notice that in a lot of these postings, the notion of love surpassing all the weight of one’s past is common. Could it blossom into something wonderful if I stay, of am I being naive? If I jet, Will I endure another 3 years of loneliness? I don’t want to go through that again.
It all started when her husband wanted to do a threesome with her and another guy
she is also married to another man. And has 3 children. ages 7, 8, and 9. I lived with her and her husband for about 3 years. She told him she didnt want to do it but he insisted. I had just recently met her through a friend, we kinda hit it off, and she chose me. I didnt want to do it at first. i have only had maybe 7 sexual partners my whole life. Anyway, we ended up doing it, it was the most awkward ive ever felt, but afterwards, she continued to be really affectionate with me sexually, even in front of her husband. He was ok with it for a while but after a month or 2 he asked her to stop. H never said anything to me about anyof it. Never considered how it would make me feel, make her feel, or anything. So needless to say, after he asked her to stop, we couldnt, and have been seeing each other ever since behind his back, even while i lived with them. He is a real weird guy who is super quiet, super passive, and a bit of a coward and a pushover. All he does is work and play videogames. Anyways
we are still together, she is still married to him, she says its for the kids, but they dont have sex or ever see each other. They have nothing in common, and the marriage seems like it was out of convenience since he got her pregnant when they were really young.
Even tho she feels bad she tells me it’s immature to hold that over her head. She makes me hang out with the gross looking 30 year old cause she says he’s her friend. I also just got back from a trip to her parents house and her stepbrother was visiting. I had to put up with him for a whole week.
She’s now so smitten with me she’s planned out her would-be wedding with me and says marry me when we are having sex. She says she’s never been loud in bed until she met me. She meant it as a compliment but it made me really upset inside. Then again she tells me how nobody has ever treated her like I have and I am the sweetest man she has ever met. We plan to go to counseling at the college and work this problem out.
I have no idea what to do. forgive the spelling and grammer, Im just really broken up about the whole situation.
