Some Advice Neded

Hello everyone!I need some feedback/advice as to where I am in life right now. First off, I am a recent college grad (23 yo) who hasn't had very good luck finding a partner. I haven't been "out" for too long. It's only been about three years. Just to give some background, I am overweight (250 lbs. 5'9) which has posed many different problems.To sum up the experience I've already had, I have been seriously interested in three different guys over the past three years. For the purpose of making a long story short, the first guy claimed to be "straight as a toothpick" but showed quite a bit of affection toward me even though he was dating a girlfriend. At one point, he even told me that my weight was holding him back from wanting things to be more serious. I told him he needed to figure things out but instead wanted to keep things as they were. We are no longer talking at this point.I then studied abroad and started to like a guy that was an American student in my program. Once again, he showed quite a bit of affection toward me but then I discovered he had a girlfriend. I brought up the feelings I had been noticing and he denied it up and down even though he broke up with his girlfriend very soon after. I then discovered him on tinder (mine was set on male seeking male) and when I asked him why he appeared, he said he "just wanted to see what other guys would think".It's hard for me to admit but I did end up getting desperate and took to grindr. I wound up in a couple of really bad situations that made me feel very uncomfortable but I was so sad/hurt I couldn't find anybody that I lowered myself to let anyone take advantage of me. I'm not going to get into specifics but the second experience resulted in my consent being disregarded and me going to the hospital.The next guy never claimed to be straight but everyone assumed he was. He had never had a girlfriend before and was showing quite a bit of affection toward me knowing full well my sexuality. Things never got too serious but they did progress enough to spark discussion about what was actually going on. This person lied at first that he had no idea what was going on but admitted later that he knew but just "didn't want to say anything". He did respond to my advances and everyone around us saw what was going on but he was in denial. He too got a girlfriend but broke up with her soon after.I'm beginning to think that I am cursed and will never find anybody that actually likes me. I am so sick of people that either want to hide their sexuality or don't know exactly what they want. It makes me feel like the test subject for these people to see what they like completely disregarding my feelings.All this considered, why does it seem I only attract straight guys looking for a shallow "check" on their own sexuality? I get very sad over what has happened especially the abuse that has resulted over my desperation. I am moving to a new area soon and I hope that this will up my chances for finding someone genuine. I feel more discouraged though that I am approaching my mid 20s without any kind of relationship. I'm not trying to pity myself by saying that I feel unlovable because I actually do.Can you please give some feedback or some help on all this?Thank you!
