Should I carry on? Is this okay? ...

Ok I need some serious advice...

In April I fell in love with someone and they were going to go away to the Navy in September so I was expecting a breakup. The feeling got so strong and I loved them. It was mutual and he decided to quit the navy to stay...

Now he has no job and doesn’t know what he wants to do and it’s all very confusing my feelings. We had a few fights recently because I didn’t know if we should carry on the relationship. He’s younger than me by 2 years and i’m his first girlfriend EVER and he lost his virginity to me... that gives me a lot of doubts because I know he’s still young and will probably leave me eventually..

So now... do I carry it on?

but there is also another situation...

On saturday night I went to a bar because it was my friend’s birthday. I’ve been looking at this really handsome guy I was super attracted to and he was looking back. Eventually he stopped me when I was walking next to him and we started talking and really connecting. We went outside to talk more and spent three hours outside the club talking. We hugged really tight to “keep warm” and I felt like we were going to kiss.. I found out he has a wife that he married when he was 16 because she got pregnant. He’s 31, I’m 20. He’s one of the most attractive guys I’ve ever met. He told me it was about 10 years since he connected with another woman or even spoken to another woman because of his wife. At the end of the night I went back to the club to grab my bag because we were going to have food but my best friend stopped me and told me not to go with him and to come home with her. We left and he was waiting for me.. But we exchanged numbers and instagrams. The next day he texted me and invited me to a house party for his friend’s birthday in two weeks. Do I go? What do I do?

He thinks I’m single...

This is all so confusing and I need to get it out of my head. Please help a girl out to make a decision..
