Opinions M22 F24

I’m M22 in a really loving relationship with a F24 beautiful woman. We’ve now been officially together for six months and we don’t have any real problems aside from each others history. Both of us hate to think or talk about each others previous partners and when doing so it almost always ends up being a really heated argument.

I’m 100% sure that I won’t do anything she wouldn’t like or cross any boundaries but I always have uncertainties and doubt when she goes out bc I know that guys are constantly hitting on her or worst of all even the previous partners as well.

She’s going on an exchange to Spain next semester and internally I’m fukn obliterated about this idea but I don’t want to seem unsupportive or restrictive so I always put on a smile and support all of her ideas and talks. I did an exchange when I was single so I saw first hand how life is abroad and that’s why I’m scared shitless.

Any comments, ideas or help?
