Hello Georgia, first let me say something about me, i am 31,Gay ,Chubby, IT geek , and Latin, right now i have been through so much with my relationships not because I’ve had too many , i had just had few but very intense , i am a long term relationship oriented and i like commitment, i am on my fourth serious relationship my first ended when i move out of the country 5 years , the second became a beautiful friendship to the point we been roommates for five years(if you want to learn how to deal with your ex and survive i think I’m your guy .. lol ) the third one broke my heart in so many pieces he hurt, humiliate me, made me lose my dream job, almost send me to jail , it was so bad that he took all i had inside and destroy it with no remorse , then i meet my actual BF, same age same interest, we click in so many levels i think he is the one but i have trust issues same as you because of my past relationship and we have along distance relationship so is even more difficult , my advice and this is how it works for me , talk to him make him understand what you been through , one of the pillars of relationships is communication , but you have to let it go and show him you are making steps towards that , allow yourself to be angry and jealous is totally normal , the problem is when you dwell on it and make it a problem and turns into anger…i have no doubt he loves me .. And i think he worth my trust so i do everything on my power to make myself trust he never has gave me a reason not to trust him.. if you love him you have to learn to let it go and trust him and talk to him don’t keep things to yourself explain to him why you feel like that and if he loves you he will understand and even make it better for you ..
