My girlfriend is 20 yrs old, I'm 25. I met her at the pool at my community and she lives directly behind me in a townhouse....I have my own condo. We have been going out seriously for 2 months. When we first met, she had a lot of guy friends texting her things....basically looking for a booty call but she would never respond or she would just say she has a b/f. So everyonce and a while she would get texts from guys and I'd get jealous of course and ask who they are. She says they are just friends, but friends dont' just say, "I miss you" or "I wnt you to be with me" So yesterday she comes over my place for dinner. She has to hurry and eat b/c she has to write a paper then come back over to watch a show with me on tv. So she leaves at like 8 and comes back at like 9:30. I ask if she did her work, she says not really. I ask her what she was doing. After a few mroe questions from me I find out she had like 2 desserts at a diner. I asked her who she went with and she says her ex-b/f. My demeanor changes totally and so does hers b/c of it. She knows I'm uneasy. I'm stunned she wouldn't tell me but she insits she didn't think it was a big deal. She went out to lunch with him like 2 weeks earlier. I knew about the lunch, i didn't know about last nite. She gets frustrated when I ask her questions, but I think I have every right to be like well wtf. Why didn't you tell me, etc. etc. How do you guys/gals think I should handle this situation. So far my "jealousy" has come up like 3 or 4 times and she and I both get really frustrated each time. We have SUCH a great time with each other and love each other dearly. She would never cheat on me and i know this. She said she wants to marry me, spend the rest of her life with me etc. But all this still makes me uneasy. I'm absolutely clueless and need advice. Please. Thanks.
